The Final Gambit by Jennifer Lynn Barnes Review: A Tension-Packed Series Conclusion

The Final Gambit is the third book in Jennifer Lynn Barnes's The Inheritance Games series, published by Little, Brown Books for Young Readers, in which protagonist Avery Kylie Grambs must survive the final weeks in Hawthorne House to claim a billion-dollar inheritance — while a kidnapping and mounting dangers raise the stakes higher than ever before. YA Books Central calls it "a thrilling and compelling conclusion" that leaves readers "equally satisfied and reeling."

LuvemBooks Verdict

Best for

Fans of The Inheritance Games series aged 15 and up who are already invested in Avery Grambs and the Hawthorne brothers and want to see the puzzle-driven, high-stakes mystery arc reach its conclusion.

Worth it if

Worth reading if you have read the first two books in The Inheritance Games series and are drawn to propulsive, twist-heavy YA mysteries where escalating stakes — including a kidnapping plot with genuine life-or-death consequences — and a wealth-versus-morality thematic undercurrent are more important to you than deep emotional interiority or richly rendered secondary characters.

Skip if

Skip it if you haven't read the earlier books in the series, prioritise fully dramatised character moments and robust secondary-character development over plot mechanics, or are hoping this finale will resolve every thread with the same nuance and depth as its set-up.

YA Books Central describes The Final Gambit as "a thrilling conclusion to The Inheritance Games series" that tackles the morality of extreme wealth, while Forever Young Adult highlights its "Mystery Mastery" and the escalating tension introduced by Toby's kidnapping. The TypedWriter (7/10) offers the sharpest structural critique, arguing that key scenes are summarised rather than dramatised, stripping nuance from character and plot — a concern echoed more mildly by laurieisreading.com, which finds the characters "falling flat" across the series. On the enthusiast side, fairfieldpubliclibrary.org calls it "fast-paced and full of twists" with "the perfect combination of resolution and shock," and bookclb.com judges it "a satisfying conclusion to a gripping trilogy" and "a must-read for fans of the series."

What Works & What Doesn't

What Works
  • Escalates the series' stakes meaningfully through the kidnapping of Toby, adding genuine life-or-death tension
  • Maintains the puzzle-and-mystery mechanics that earned the series its devoted following, per Forever Young Adult
  • Converges Avery's fortune, safety, and relationships into a single high-pressure climax
  • YA Books Central calls it a 'consuming and mysterious journey' that satisfies as a series conclusion
What Doesn't
  • Key scenes are summarized rather than dramatized — a structural choice that, as The TypedWriter notes, reduces nuance in character and plot
  • Several supporting characters, including Nash, Xander, and Avery's sister, receive limited development according to some critics
  • Functions exclusively as a series continuation — readers unfamiliar with the first two books will be lost from the opening pages
This review covers the book's content and published reception; it is not based on hands-on reading.

What the Story Delivers

The Final Gambit picks up with Avery Kylie Grambs just weeks away from completing her year-long stay at Hawthorne House and claiming the astronomical fortune left to her by the late Tobias Hawthorne. The path to that inheritance, however, is anything but straightforward: the paparazzi are tracking her every move, financial pressures are compounding, and the kidnapping of Toby — a figure central to the Hawthorne family's secrets — introduces genuine life-or-death stakes into a series that had previously kept its dangers somewhat more contained. Barnes keeps the engine running on the same puzzle-and-mystery mechanics that drove the first two books, while threading in questions about the morality of extreme wealth and the power it concentrates.

Place in the Series

As the third book in The Inheritance Games series, The Final Gambit functions as a culminating chapter for the arc begun when Avery first arrived at Hawthorne House as an unlikely heir. YA Books Central's Jan Farnworth describes it as "a thrilling conclusion to The Inheritance Games series" and notes that the book "challenges the morality of such power — a theme worth exploring." Forever Young Adult similarly observed that the novel "ramped up the tension with Toby's kidnapping," marking a notable escalation from the earlier entries. For readers who have followed Avery's journey through the first two books, this installment is designed to pay off the threads laid across the series.

Strengths: Puzzles, Pacing, and Stakes

The book's most consistently praised quality is its puzzle-and-mystery construction. Forever Young Adult highlighted its "Mystery Mastery" and true-crime energy, placing it in conversation with other high-tension YA thrillers. The kidnapping plot injects urgency that critics noted was a step up from the series' earlier stakes, and Barnes's command of the page-turning rhythm that made the first book a phenomenon is again on display. YA Books Central calls the reading experience "consuming and mysterious," and the series' dedicated fanbase has responded enthusiastically to the way Avery's fortune, life, and romantic entanglements all converge in the final act.

Limitations: Character Depth and Scene Construction

Not every element earns equal praise. The TypedWriter awarded the book a 7/10 and raised a pointed structural critique: key scenes — including an early sequence in which Jameson takes Avery out for her birthday — are summarized rather than dramatized, which the reviewer argues strips nuance from both character and plot. The same source finds several supporting characters, including Nash and Xander among the Hawthorne brothers, underdeveloped, and notes that figures such as Avery's sister and her best friend Max feel peripheral to the story's real concerns. These criticisms suggest that readers who came to the series primarily for its romantic or character-driven dimensions may find this installment skewed heavily toward plot mechanics at the expense of emotional interiority.

Who Will Get the Most From It

The Final Gambit is aimed at readers aged 15 and up and is pitched at a grade 7-and-above reading level, according to the publisher's listing. It is built for fans who are already invested in Avery, the Hawthorne brothers, and the labyrinthine secrets of Hawthorne House — this is not an entry point. Readers drawn to the series for its propulsive mystery plotting and escalating twists are the most natural audience. Those who prioritize richly drawn secondary characters or fully rendered emotional scenes may find the book uneven, but for the core fanbase of The Inheritance Games, the conclusion delivers the resolution the series was building toward.
