Shadow Princess

I came into Shadow Princess right after The Reckoning left me annoyed and hooked in equal measure. That third book ended with a separation and a secret about the twins that I could not shake, so I ordered book four the same week. Shadow Princess is the fourth book in the Zodiac Academy series, first published in 2020, written by Caroline Peckham and Susanne Valenti. The edition I used for facts is the Independently Published paperback, which runs 622 pages. It picks up after the lunar eclipse and finally answers the Order question that hung over the first three books, then replaces it with a worse problem.

The hook is direct. Tory Vega and Darcy Vega are Gemini twins, joint heirs to the Solarian throne, students at a school that spent a year trying to drive them out. At the end of book three, Lionel Acrux forced them through a shadow ritual in a crater off campus. Darius Acrux and Professor Lance Orion were there too. All four came out marked. Lionel used Dark Coercion to make them forget the night. It did not hold on the twins. Their fire burned through it. Lionel walked away thinking their Order was Dragon. He was wrong, and the truth is the kind that gets people killed in Solaria.

What hit me first is how tired everyone is. Tory is angry in a focused way now, less performative than in book one. Darcy is softer but less willing to bend. Darius is fraying. Orion is carrying research he does not want to share yet. The book lets that exhaustion sit on the page. Classes continue. Meals continue. Patrols continue. Underneath, four people are trying not to let shadows leak out of their eyes in public.

The night none of them were supposed to remember

The opening chapters deal with fallout. Tory and Darcy remember everything from the crater, including the way shadows moved through them and stayed inside. They agree to tell almost no one. Darius gets them to a treehouse sanctuary at King's Hollow soon after, and that scene sets the terms for much of the book. The twins are Phoenixes. Not Fire Harpies. Not late bloomers. Phoenixes, unseen in Solaria for more than a thousand years.

Orion lays out what that means in plain terms once he finishes his research. Phoenixes resist mind magic, including Dark Coercion. They resist Siren lure. Fire does not hurt them. They feed fire back. They can hurt Dragons, which matters a great deal when the most dangerous family in the country is Dragon led. Tory blasts Darius across a room when he reaches for her too fast, and the moment works because it is not played as triumph. She is scared of what she did. He is scared of what it means that Lionel misread them.

The secrecy oath follows. Max Rigel pushes the Heirs toward honesty in a way I did not expect from him. He drops his shields and lets the others read him, and what they find is years of pain held behind a calm front. That scene reframes Max for the rest of the book. Caleb Altair admits to nearly killing a newly Awakened girl once, a debt his mother paid off. Darius cannot answer direct questions about his father, so Max reads around the block. Lionel has used Dark Coercion on Darius since his Awakening. Lionel beats Xavier for involuntary shifts after his Pegasus Order emerged. None of this excuses what the Heirs did to the twins. It does explain why Darius flinches when orders sound like his father.

One small beat I appreciated: Tory goes still when Darius names Xavier as the reason he stood down at the ritual. She walks away instead of swinging. That restraint feels earned after three books of swinging first.

Learning to carry shadows

Because the ritual left shadow magic inside all four of them, training becomes secret and urgent. Orion and Darius take the twins to Air Cove, a quieter stretch where they can practice without an audience. The rule they learn fast is that shadows feel good. Warm. Euphoric. Attentive. That is what makes them dangerous. A shadow touched Fae needs an anchor with a strong emotional bond to pull back from the pull. Tory and Darcy choose each other instead of relying on Darius or Orion, and the book returns to that choice whenever one of them wobbles.

Practice scenes are specific and physical. They lure shadows in, then try to banish them. Tory draws first with Darcy as anchor, and the shadows tell her to kill Darius. She resists because Darcy holds on, not because she masters a technique. Later Darcy tries a silencing bubble in Cardinal Magic and passes out from the call. She decides they have to tell Orion more than they planned, even though Tory does not trust him or Darius fully yet. Orion is devastated when he hears how bad the pull is, but he agrees to help and brings blood magic and a draining dagger into the work.

Diego Polaris becomes important here in a way that surprised me. He visits Darcy and admits two things at once. His family uses dark magic, and his grandmother's soul magic bonded them to the place shadows come from, which is why he can sense what sits inside Darcy, Tory, Darius and Orion. His uncle Alejandro works for Lionel and was placed near the twins to pass information. Diego says he gave nothing of value and pledges himself to the Vegas. Orion listens from the next room and does not trust a word. Darcy forgives Diego faster than Orion likes. She tells Orion she will not let a man dictate her friendships, and the argument that follows feels like two people who care about each other talking past the actual fear, which is losing control.

Darcy and Orion also discover that their combined power steadies the shadows. Each can anchor the other for short stretches. Orion power shares with Darcy and admits he suspects they are Elysian mates, a fated bond in this world. He tells her he is teaching Darius dark magic to use against Lionel one day, the same kind of magic tied to his own father's fate. Those confessions raise the stakes for their secret meetings. If the Council learns a professor is power sharing with a student heir, both lose protection.

Secrets, blackmail and a Halloween mess

School does not pause for secret training. The middle of the book stacks classes, parties and confrontations, and this is where my patience thinned in places.

The Halloween party in the Earth Caverns is the set piece. Tory dresses as a Pegasus, a choice that cuts Caleb deeply enough that he ends their intimate relationship. Seth Capella discovers Darcy and Orion together and uses it. He blackmails Darcy and forbids her from telling Tory, which isolates the sisters at the worst time. At the party itself, the Heirs use potions to warp perception. Darcy hallucinates ravens. Tory behaves in ways that damage her standing. The next day brings the familiar cycle of whispers, screenshots in spirit if not in name, and teachers looking elsewhere.

I found these chapters uneven. The costume misunderstanding with Caleb is sharp and sad. The blackmail with Seth is cruel in a way that fits his fear of tenderness. But two party scenes run long on spiked drinks and public embarrassment, beats we saw in books two and three. I skimmed parts of the second dance because I could predict who would humiliate whom and when laughter would cover it.

What kept me reading was the quieter pressure around the secrets. Professor Washer nearly catches Darcy in Orion's room. Orion has to talk fast while Darcy hides. Caleb seeks Tory out and then pulls back when friends watch. Seth does something kind for Darcy and ruins it with a crude line because kindness scares him. Sofia Cygnus stays loyal without powers to trade, sharing clothes and study time and walks to class. Geraldine Grus barges through tension with loud loyalty that gave me room to breathe. Diego keeps showing up for Darcy even as Orion warns her off. These small loyalties matter more than the big speeches.

The Shadow Realm thread tightens here too. When Darcy and Diego's hands touch by accident, their shadow touched power merges and Darcy falls through into grey stillness. A girl calls for help and begs for a bridge back. Orion recognizes the description. It is Clara, his sister, long thought dead. She calls herself the Shadow Princess. Tory gets pulled separately later. Something with sharp teeth and black pits for eyes grabs her arm. Her Phoenix fire burns it off and throws her back, but the wound is hard to heal. Shadow wounds resist normal care. Orion runs low trying to close it. Both twins agree to help him bring Clara back, though Tory still questions his loyalty and he answers that Lionel is the worst enemy in their world, so they need the Heirs whether they like it or not.

Christmas at the Palace of Souls

The Christmas section at the Vega palace is my favorite stretch, and it slows down enough to let history breathe.

The twins arrive before the Celestial Council and explore their mother's rooms. Behind a waterfall, a hidden cave opens only to their combined touch. Inside are two silver rings engraved with R and G and a Tarot card, The Sun, with a handwritten line about wings and justice and saved blood. A mirror in their mother's closet releases stored visions when both twins touch it. They see their parents together. They see their mother foreseeing their Phoenix Order. They see her making them Changelings, placing them with mortal families to protect them from an attack she saw coming. The last vision shows the twins on the throne together with a dark shape opposing them and not winning. In the ballroom, where wings meet golden scales, another combined touch opens a passage and releases a vision of a young Astrum escaping on the night of the royal murders while guiding a raven haired boy by the hand.

None of this is delivered as a lecture. The twins argue about what the visions prove. Darcy wants meaning. Tory wants proof. I liked that split. It felt like sisters, not like mouthpieces.

Then the Council arrives uninvited with the Heirs and their families, and the holiday turns performative. Lionel pushes abdication at dinner, pressing the twins to give up their claim. Tory baits him. Darius sits beside her, says quietly that she is not unwelcome, and apologizes for ruining the day. It is a small apology next to large harm, and the book does not oversell it. Seth engineers a kissing arch so Darcy passes through with Orion instead of Catalina. Orion kisses Darcy's cheek and says nothing audible. The restraint in that moment says more than a speech would.

Criticism belongs here too. The palace chapters introduce a lot of objects and visions quickly. Rings, cards, mirrors, passages. I had to reread the mirror sequence to track which vision showed what. A little more space between reveals would have helped. Still, the emotional throughline holds. Tory and Darcy do the math of rent and thin walls even while offered silks and titles. They do not romanticize power. They know what having nothing costs.

A public reveal and a private refusal

Two turning points carry the back third, one public and one painfully private.

The public turn comes during a Nymph attack. Lionel and Melinda are nowhere to be found when the palace comes under assault and the defense starts losing ground. Darcy and Tory choose to shift into full Phoenix form in front of witnesses and burn through the attackers. The Fae who see it are ecstatic. The Vega queens are Phoenixes. Lionel is furious. Orion pulls the twins back to Zodiac Academy fast to keep them from press and Council pressure. The political calculation shifts in one night. They are no longer rumored threats. Their power is visible, and visible power draws both followers and knives.

The private turn is the Divine Moment. On New Year's Eve, a blizzard pulls Darius and Tory separately from the group. Neither chooses to walk out into it. The stars pull them. At the storm's center, in a bubble of stillness, Darius tells Tory they are Elysian Mates. Leo and Gemini aligned. He apologizes and offers her everything without defense. Tory refuses. She says the history of what he did cannot be separated from who he is, and she will not build on that foundation. Black rings form around both their pupils. They are Star Crossed now, marked by a refused fate.

I sat with that refusal for a day. Part of me wanted acceptance for the ache of it. A larger part respected the no. The book spent three and a half volumes showing harm, not hinting at it. Forgiveness that arrives because stars align would cheapen Tory's anger. Darius shifts and roars into the sky. Tory runs back through snow. Neither looks noble. Both look hurt. That felt honest.

Darcy and Orion's parallel pressure is quieter but just as heavy. Their meetings risk exposure. Seth's blackmail still hangs over Darcy. Orion keeps preparing for a crossing he may not survive. The book does not present their bond as clean. It presents it as chosen under bad conditions, which is different from fated and easier to believe.

The rescue that breaks everything

The final movement is a rescue planned by four and carried out by two.

Orion prepares a sea cave with everything needed to cross over and pull Clara back. The plan needs Darius and Tory alongside Darcy and Orion. Neither Darius nor Tory arrives because the storm takes them first. Orion and Darcy choose to go anyway, using dark stardust, blood magic and Darcy's Phoenix power to fuel the crossing. The place they enter is grey and still and airless. Clara is there, thin and pale, wearing shadows like a cloak after years inside. Orion builds a bridge with the stars and uses Darcy's magic as fuel. All three land back in the cave.

Clara is not herself. Years inside left her hollowed and furious. She blames Orion for leaving her. He tries to explain he did not know she lived. She does not hear him. She takes up the draining dagger, drains him, drives the blade into his stomach, then flees into the storm at Vampire speed. Darcy is out of magic. Orion is weakened. They cannot stop her.

Darcy ties her jacket around the wound and stays with him. He tells her the last months were the happiest of his life. He asks her to promise she will claim the throne and work with the Heirs, and to understand that Darius is not his father. She promises. She tells him she loves him. He goes still. Darcy runs from the cave and ignites the sky with blue and red Phoenix fire, screaming for help with nothing left in reserve.

That ending works because it withholds the conversation the characters should have had earlier. Orion should have told Darcy more about Clara's state. Darius and Tory should have talked before the storm took them. The adults should have stopped preparing children for crossings. The book knows this. The frustration I felt was the point, though I still wanted one more honest chapter before the cut.

For who this is for, do not start here. Start with The Awakening, then Ruthless Fae and The Reckoning. You need the bullying history for the small kindnesses to register and the trial history for the Phoenix reveal to hit. If you want gentle school stories or closed door romance, look elsewhere. This one is loud and violent and sentimental by turns, with crude jokes, blood magic, coercion used as a weapon, and a Fae court logic where insult and flirtation share language. The middle sags in party scenes. Dialogue tags repeat. Smirks and growls pile up until they blur. Coercion and compelled truths are sometimes played as romantic when they should be named as violations, and I wish the book paused more often to let a character say what happened plainly.

Still, I finished and looked up book five immediately. Tory's refusal feels earned. Darcy's promise feels heavy rather than noble. Darius reads less like a wall and more like a scared son under his father's hand. Caleb and Seth and Max read like boys with different ways of showing fear. The twins' Phoenix fire is out in the open now. Clara is loose and corrupted. Orion's life hangs in the balance. The throne question is no longer abstract. That is what a series middle should do. It made the world bigger while making me care more about the people inside it, even as I wanted to argue with several choices on the page.
