Would you become a fugitive to save your child? Another astonishing high-concept hook from the author of million-copy bestseller Wrong Place Wrong Place

A road trip across America with her teenage daughter was meant to be much-needed bonding time for Simone before Lucy leaves home for university.

But on the first night of their stay, in a cabin deep in the Texan desert, Simone wakes to find Lucy missing and a mobile phone in her place. The phone rings and the voice on the other end issues instructions: Don’t tell the police. Come to this location. Be prepared to do a deal…

There is nothing Simone wouldn’t do to save her daughter. Hide the truth. Commit a terrible crime. Become a wanted woman.

But there’s one thing Simone hasn’t considered.

What if this is just what the kidnappers want?

Bravura novel writing

IAN RANKIN

An utterly original kidnap story that throbs with tension—hard to put down.

Shari Lapena

Gillian McAllister has done it again! This is such a clever, tense and twisty book, I inhaled it in under a day. The pacing is perfection and the twist, when it comes, is deeply satisfying, but it is the characters that elevate Gillian's books into the best of the best,

LISA JEWELL

As moving as it is gripping, this superior thriller is, more than anything, a testament to the power of a mother’s love

Sophie Hannah

Caller Unknown sets a new standard for modern thrillers - you’ll gasp, you’ll cry, you’ll never forget this story.

Holly Seddon

A taut, heart-in-mouth action thriller. With Gillian McAllister’s trademark beautiful writing, not only is Caller Unknown a wonderfully atmospheric and twisty read, it’s also a powerful ode to motherhood. I couldn’t put it down. Absolutely superb

CLAIRE DOUGLAS

An unputdownable adventure that was both heartwarming and thrilling! Everything I've come to expect from Gillian McAllister!

FREIDA MCFADDEN

A propulsive, page-turning thriller that's the very definition of a "one-more-chapter" novel. What sets it apart is its beautiful characterisation of maternal love and sacrifice. It's a sure-fire bestseller.

HANNAH BECKERMAN

Utterly HOOKED! I was journeying through that desert, living every twist, turn and surprise. Immersive, heart-pounding and astoundingly brilliant.

LUCY CLARKE

Another terrifically tense thriller from a writer at the absolute top of her game

Tense, twisty, and an emotional gut punch—CALLER UNKNOWN is a one-sitting read.

Chilling, immersive, atmospheric and poignant; Caller Unknown is beautifully told, with a wonderful trademark McAllister twist that fans will hope for but still not see coming. Masterful.
