Critics Review

An unputdownable adventure that was both heartwarming and thrilling! Everything I’ve come to expect from Gillian McAllister! – FREIDA MCFADDENGillian 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 JEWELLTense, twisty, and an emotional gut punch—CALLER UNKNOWN is a one-sitting read. – KARIN SLAUGHTERA 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 DOUGLASChilling, 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. – ANDREA MARAAn utterly original kidnap story that throbs with tension—hard to put down. – Shari LapenaAnother terrifically tense thriller from a writer at the absolute top of her game – ERIN KELLYUtterly HOOKED! I was journeying through that desert, living every twist, turn and surprise. Immersive, heart-pounding and astoundingly brilliant. – LUCY CLARKEUtterly compelling, gripping and so entertaining! – LIZ NUGENTAs moving as it is gripping, this superior thriller is, more than anything, a testament to the power of a mother’s love – Sophie Hannah
