Caller Unknown: A Read With Jenna Pick

A READ WITH JENNA BOOK CLUB PICK AS FEATURED ON TODAY • "An unputdownable adventure that was both heartwarming and thrilling! Everything I've come to expect from Gillian McAllister!" —Freida McFadden, #1 New York Times Bestselling Author

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.

Unbearably tense, compassionately told, and full of well-crafted moral dilemmas, Caller Unknown proves once again why Gillian McAllister’s thrillers are “the best of the best” (Lisa Jewell).

Hello there!

As you find me, it's spring 2026 and my new novel is Caller Unknown, a thriller with a mother and daughter at its centre. It asks the question: if a ransom contains instructions to get your daughter back that tell you not to tell the police, do you comply? What if that includes your husband?

My most popular novel is probably Wrong Place Wrong Time, which was selected for the Radio 2 book club and was the Reese's Book Club August '22 pick. It debuted at number 4 on the Sunday Times Bestseller List and number 2 on the New York Times Bestseller List. Famous Last Words was a Sunday Times bestseller in paperback and hardback and a New York Times bestseller too.

When not writing (which is basically never), I can be found walking my dog Wendy and parenting my small toddler. The best moments of my day always are the first sip of my coffee, the moment I step into the bath at night, and my son telling me he loves me. And that rare thing that happens only once a year - a novel idea.

I love instagram - come find me over there as gillianmauthor. I talk about real life, how hard writing is, and what to do when your body breaks (as mine does, from time to time).
