Synopsis:
How far would you go to rescue your child? A mother races against the clock—and finds herself on the wrong side of the law—in a desperate fight to save her teenage daughter in this pulse-pounding thriller from the author of Reese’s Book Club Pick and New York Times bestseller Wrong Place Wrong Time.
There is nothing that Simone won’t do for her daughter, Lucy. The two have always been close, and with Lucy about to leave home for university, they depart the UK for a vacation to Texas to spend some quality time together. But when Simone awakens on their first morning in the desert, Lucy is gone, missing from their rental cabin. In her place is a cell phone, and a voice on the other line issues a shocking ransom demand. Don’t tell the police. Come to this location. And be prepared to do a deal…
Though Simone’s husband urges her to bring in the authorities for help, she knows she can’t take any chances. The kidnappers might kill Lucy if she tells anyone. No mother would take that risk. Instead, that night, she drives to the isolated meet-up.
What she finds there changes everything. The mysterious kidnapper doesn’t want money. They want Simone to do something. The unthinkable.
A catastrophic chain of events is set in motion, with chilling consequences that extend beyond Simone and her family. What follows is a heart-pounding journey through the small towns and punishing deserts of remote Texas, in which Simone’s courage—and morality—is pushed to the brink as she discovers what it truly means to be a mother.
Review:
Caller Unknown by Gillian McAllister is the kind of high stakes, emotionally charged thriller that pulls you in immediately and refuses to let go. From the very first chapter, the tension is relentless as Simone is thrust into every parent’s worst nightmare, her daughter missing, and she receives a chilling set of instructions that force her into impossible choices. The pacing keeps you on edge, constantly shifting direction in ways that make it nearly impossible to predict what’s coming next. It’s twisty, gripping, and deeply rooted in that central question: what would you do?
What really elevates this story is how character driven it is. This isn’t just about the race against time—it’s about Simone’s unraveling sense of morality as she’s pushed further and further beyond her limits. McAllister leans hard into the emotional stakes, exploring just how far a parent will go to protect their child, and it makes every decision feel weighty and personal. Even when the plot veers into far fetched territory, it’s easy to go along for the ride because the intensity and emotional core are so compelling. Honestly, when a thriller is this action packed, you kind of want it to go there.
There are a few moments in the middle where the pacing slows down, but even then, the story never lost my attention. Those quieter sections give space to process the moral dilemmas and deepen the character work, which ultimately makes the high intensity moments hit even harder. Tense, emotional, and full of unexpected turns, Caller Unknown is a gripping reminder that sometimes the most terrifying question isn’t what’s happening, but what you might be capable of when everything is on the line.
Overall rating: 4/5
