I started The Final Gambit the night I finished The Hawthorne Legacy because I could not leave Toby out in the cold again. Book two ended with him handing back a metal disk and walking away, with Eve hidden and Tobias still pulling strings from the grave. I wanted answers more than sleep. I got them, plus a chess clock, a private island, a violent creditor, and a love choice I had been dodging for two books.

This is the third book in The Inheritance Games series by Jennifer Lynn Barnes, published August 30, 2022 by Little, Brown Books for Young Readers. The US hardcover runs 358 pages with ISBN 9780316450431. It is told in first person by Avery Kylie Grambs and picks up soon after book two. Avery must still live in Hawthorne House in Texas to keep the billions Tobias Hawthorne left her. Nash, Grayson, Jameson and Xander return, plus Libby, Max, Alisa Ortega, Oren, Skye, Zara, Thea and Rebecca. Read the first two first. This one spoils them on every page.

The setup is tight. Tobias left one more game for Avery and the brothers, with Toby and Eve at the center and a dangerous outsider ready to collect. Avery has weeks left on the year condition. If she leaves Hawthorne House, the money goes to charity. If she stays, she plays in public while people who want the fortune press harder. I liked that pressure. A meal matters. A hallway matters. A flight matters.

Eve moves in

Eve is Toby Hawthorne's biological daughter and younger half sister to Mellie and Eli. At the end of book two we learned Mellie and Eli took house jobs to force Toby out so he would provide for Eve, and Mellie shot Sheffield Grayson to stop him killing Toby and Avery. Now Eve steps forward. She is sharp, watchful, polite in a way that hides hurt. Tobias named her in a late codicil. If Avery fails or quits, Eve is next in line.

Barnes does not turn Eve into a pouting rival. Eve grew up passed between people who wanted money from Toby and Tobias. She learned to read rooms fast, the same skill Avery learned in Connecticut, but with less warmth around it. When Eve asks for normal things, a room of her own, time with Toby, a straight answer about school, she sounds younger than she tries to act.

Avery wants to like her and fears her, which felt honest. On paper Eve is a backup heir. In the house she is a tired teen who flinches at loud voices and covers it with jokes. Libby notices first. She knows what it means to feel extra in a rich house. She brings Eve food, shows her which stairs creak, tells her where to hide when reporters circle. Xander brings gadgets and snacks and fast talk that gives Eve room to breathe.

The strain is legal too. Alisa explains Eve does not have to act to inherit if Avery slips. Zara loves any crack in Avery's claim. Skye cries about family and counts exits. Oren adds staff, changes routes, sets rules about who can be alone with whom. Avery sleeps less, counts tiles, checks windows. She worked for a year to belong there and now shares air with the one person who could replace her without trying.

Vincent Blake collects

Every rich house story needs someone money cannot scare. Here it is Vincent Blake. He runs an underground gambling ring, fixes contests, collects debts with threats rather than paperwork. He is also Eve's maternal grandfather and the man Mellie and Eli owed. He smiles while he names what you love, which makes him worse.

Blake says Toby owes him. Years ago Toby needed cash and cover to stay hidden and keep Eve fed, and Blake provided both at a price. Now Blake wants payment with interest, plus a prize only Tobias could lock away. He offers Avery a deal. Bring the brothers, solve what Tobias left on Hawthorne Island on his timeline, and he will clear the debt against Toby and Eve. Refuse, and Eve pays, or Toby pays, or Libby pays.

He works because he studies people. He knows Jameson cannot resist a wager. He knows Grayson will step in front of Avery. He knows Avery cannot walk away if a friend is at risk. Sit down. Have tea. Look at these photos of your sister at school. He lets silence do the rest.

Oren wants Avery nowhere near him. Alisa wants everything on record. Nash wants to put him through a wall. But Blake holds paper and blood ties to Eve, which gives him reason to be at the door that lawyers cannot fully block. Avery agrees to more than she should because Toby is gone again and Eve is in her house eating cereal and trying not to cry when the phone rings.

Blake stays scary without gore. Barnes keeps threats short. A name. A school. A time. A photo taken too close. That restraint lands harder than a speech. I believed Avery when she said her hands shook after he left.

Chess and Hawthorne Island

Tobias loved chess the way other rich men love boats. He played to win and hid messages in openings and endgames. Avery learned the game in the park for cash against Harry, who was really Toby, without knowing she was getting lessons from a Hawthorne. That link becomes the key to the last game.

The final game centers on Hawthorne Island, where fire years ago killed Kaylie Rooney and two boys and left Toby burned and guilty. Tobias bought silence, paid families, kept files, and built a fresh puzzle into the island property. Blake forces the timing. Tobias set the board. Avery, Jameson, Grayson and Xander have to play, with Eve tied to the outcome.

I will keep steps light so you can enjoy solving it. A chess problem points to places on the island. Each place holds part of a larger lock. Each lock needs two minds at once, one to see pattern and one to see people. There are boathouses and marked stones, a hall with a giant board, timers that force choices, rules about who can touch what and when. Tobias loved rules that turned family into pieces.

What I liked was how physical it feels. Wind. Salt. Wet shoes. Bad light. A clock ticking while gulls cry and a boat waits. Avery misreads a position and has to resign a line and start over. Xander drops a tool and swears. Grayson stands too still, thinking about law as well as wood. Jameson laughs when he should not, then goes quiet when he sees Avery is scared. Eve watches and learns fast, which both helps and hurts, because Blake watches her too.

Barnes shows chess without drowning us in notation. She names ideas enough to feel real, forks, pins, pressure where any move weakens you, but keeps focus on choice under time. Avery is good because she stays calm and spots what people protect. She learned that playing for rent money. A rich boy plays to show skill. A poor girl plays to eat. That edge matters on the island.

If you love puzzles, this is the payoff for three books. Middle names as maps in book one. Hidden ink and charities in book two. Now chess as memory. Tobias taught Toby, Toby taught Avery without telling her, and now Avery has to prove she learned.

What Toby did and why Tobias chose Avery

Toby Hawthorne II grew up as the younger son of a man who treated children as projects. As a teen he learned he was adopted, pieced it together alone, and felt lied to by everyone. He fell in with friends who were trying to get clean at Camden House, including Kaylie Rooney. They spent time on Hawthorne Island. One storm night, angry at Tobias, Toby soaked parts of the house in accelerant and opened gas lines, meaning to burn an empty building as payback. Before he lit anything, lightning struck. Fire took the house with his friends inside. Toby lived, barely, with burns and guilt that never healed.

Hannah Rooney, Kaylie's sister, found him with help from fisherman Jackson Currie near Rockaway Watch in Oregon and nursed him for weeks. They loved each other for a time. It broke under grief and fear and Tobias watching from far off. Hannah changed her name to Sarah, raised Libby and Avery with little help, hid love notes in postcards with heat reactive ink. Toby drifted, played chess in parks as Harry, watched Avery without telling her. The night Avery was born in a storm, he delivered her and signed Ricky Grambs name on the certificate to shield Hannah. He always thought of Avery as his in feeling, though DNA later proved Ricky was her biological father.

So why did Tobias leave billions to Avery. The book answers it straight. Tobias watched Toby love Hannah and watched Hannah raise a girl who stayed calm, solved fast, and protected her sister. He saw Avery play chess with Harry and hold her own. He needed someone who could draw Toby out, survive his family, and finish his games without turning cruel. Eve was too young and too exposed to Blake then. His grandsons were too shaped by him. Avery was outside the house but formed by the same skills. He chose her as player and bait at once. Avery does not forgive him fast. Neither did I.

Toby's return scenes are quiet and strong. Older, thin, moving like burns still pull. Funny in short bursts, then gone flat. He wants Eve safe and Avery free and himself elsewhere, because he thinks his presence harms people. Avery begs and argues. Eve goes still and listens too hard. Those pages carry the book. A father who failed, a girl who needed more, a young woman between them who refuses cruelty even when tired.

Grayson, Jameson and the choice

Grayson offers care and order. Jameson offers fire and play. Avery cares for both and the books let her feel it without shaming her.

Grayson here is steadier than in book one. He guards doors, takes lawyer calls so Avery can eat, tells her when a move is legally risky. He stands between her and Blake without a speech. He also holds back. He was raised to be heir, lost it, learned his biological father was Sheffield Grayson, and now watches Eve shift the line again. His scenes with Avery are gentle and sad. A coat offered in wind. Advice given softly, then withdrawn.

Jameson runs hot from page one. He needs the hunt the way some people need air. He bets, he climbs, he teases, he goes quiet when Emily's memory rises. Emily Laughlin still shadows him, the girl who played him and Grayson against each other and died before Avery arrived. Jameson fears he only wants what he cannot solve. Avery fears she is another puzzle to him. They test it with talk, not just kisses. About fear. About Toby. About what happens after the year ends.

Avery chooses Jameson. She tells Grayson straight, kindly, without games, and tells Jameson what she needs. No more bets where she is the prize. No more vanishing when feelings get loud. I found it fair because the book earns it through work together. They solve side by side. They cover each other on the island. They argue about Blake and make up with plans, not just touch. Grayson takes it with grace that costs him. That short scene on the boat back stayed with me longer than the kiss.

The kisses stay heated but not explicit, in line with young adult range. Consent is asked and given. Libby teases. Xander knocks at the worst time. Eve pretends not to see.

Back at Hawthorne House, reporters camp at gates. Zara pushes lawyers. Skye performs worry while counting angles. Max keeps Avery human with homework talk and fierce loyalty. Libby grows fast, holding a job and holding Eve's hand. Nash and Libby move toward something steadier, built on cars and quiet. Xander rigs lights, maps tunnels, talks Eve through panic with clear steps. Oren checks boats, changes codes, tells Avery no and means it, then finds a safer yes. Those small beats kept me tied to people when chess could have taken over.

What bugged me and who should read it

My main gripe is one fans will know. Puzzles sometimes matter more than people. A clue opens right when talk gets hard. A timer rings before tears fall. Emily gets mentioned but not fully faced. Zara gets sharp lines but little softening. Skye gets schemes but little reckoning. Even Toby gets fewer quiet pages than he deserves once the last lock clicks. I wanted one more chapter of Toby and Eve eating soup and saying nothing clever at all.

Avery also solves fast. She spots chess motifs, reads Blake's tells, cracks wordplay under pressure, handles press with poise she lacked in book one. Growth explains some of it. A year of living in puzzles would train anyone. Still, I wanted one lock to resist for a full day, to make the win ache. Blake folds a bit quick at the end for a man built up as patient. The final reveal about Tobias's last layer is clever but relies on Avery guessing exactly right under a clock. Fun, yes. Fully fair, not quite.

Pacing runs fast, sometimes too fast. Planes wait. Wounds heal quick. Lawyers appear on cue. Police take a back seat to teens with flashlights. If you need strict realism, you will sigh. I sighed twice and kept reading because the emotional logic holds even when logistics stretch.

Still, if book one hooked you with secret passages and book two hooked you with Hannah's postcards, book three pays off. You get Eve and Blake as fresh blood, chess as memory, the island as stage, Toby's truth told plain, and Jameson chosen with clear terms. Chapters end on hooks. The house still surprises.

Pick it up if you like young adult mystery with puzzles, billionaire stakes, and warm romance. Skip it if you want slow realism or a hard look at wealth. Money here buys planes and lawyers and new trouble that needs more money to fix. Barnes uses it as fuel rather than question.

What stayed with me was not a cipher. It was Avery telling Eve she could stay even if the will did not require it. After three books where people were moved like pieces, one girl offers another girl a room with no strings. Tobias built a maze. Avery opened a door. That felt like winning.
