Ten days. Too many secrets. No way back.

White sand. Blue sea. Absolute privilege.

Charlotte settles back in her sun lounger with her baby daughter as her husband and two sons play nearby. Their surroundings could not be more exclusive, the location idyllic. The company though, is less than idyllic: her husband's business partner and the woman he left his wife for.

And then Charlotte catches sight of someone she has not seen in years.

Gemma was once her closest school friend. Now she's a journalist, mysteriously on a press trip at the very same exclusive resort - and asking questions Charlotte would rather not hear.

Because despite her claims, Gemma didn't come for a review.

She came for the truth.

And these ten days will change everything.

A masterclass in exquisitely plotted summer suspense, Katherine Faulkner's new book is a must-read. Twisty, taut and as essential for your holiday as your sunglasses and sun cream. Pre-order it now.
