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

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

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

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.

LUCY CLARKE

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

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.
