"A fun, rapid fire thriller crammed full of domestic drama. Unputdownable." -John Marrs

Luxury villas on hot white sand, views for miles over turquoise water.

Flawless hostess Penny gathers guests to an island for her husband's birthday celebrations. But she soon regrets inviting self-obsessed Eloise...When a child vanishes on the night of the party, their perfect island weekend is ripped apart.

Even paradise harbours murky secrets...

Has he been taken? Has he drowned? In the panic to find any trace, Penny casts about for someone to blame-even if that person is her own daughter, Rosie.

Even clear waters descend to pitch black...

But it's not the first time Rosie's been attacked by her mother. And it's not the first time she's turned to Eloise for support. As the sun beats down and dark secrets rise to the surface, can they find the missing child before it's too late-or will this sudden disappearance endanger them all?

...and someone among them knows the whole shocking truth.
