From the internationally lauded author of Greenwich Park, The Other Mothers, and The Break-In comes a brand-new thriller set over the course of a luxurious Greek holiday where every guest has something to hide, featuring her signature double-twists.

Alex isn't sure why her workaholic husband Ludo is so eager to repeat last year's holiday in Corfu with their wealthy 'frenemies' Letty and Hector. At least they'll be at the Elia—one of the most luxurious family resorts in Europe—where there is champagne on tap, yoga at sunrise, and round-the-clock kids' entertainment to give her and Ludo a break.

The holiday felt claustrophobic enough with Letty and Hector in tow—but Alex is thrown further off-balance by the presence of her former school friend, Gemma, now a journalism teacher and amateur sleuth, who is holidaying at the resort for the same ten days.

As Gemma begins to dig into the death of a resort worker, a tangled web of secrets and lies, involving Alex, the resort, and why exactly the two women stopped speaking so many years ago, threatens to blow up their carefully curated lives.
