Instant #1 International Bestseller

Written with the chilling, twisty suspense of The Wife Between Us and Something in the Water, a seductive thriller about identical twins, greed, lust, secrets, and deadly lies.

Twin sisters Iris and Summer are startlingly alike, but beyond what the eye can see lies a darkness that sets them apart. Cynical and insecure, Iris has long been envious of Summer’s seemingly never-ending good fortune.

When Summer calls Iris to Thailand to help her sail the family yacht to the Seychelles, Iris has secret hopes for what might happen on the journey. But after a disturbing incident in the middle of the Indian Ocean, everything changes.

Now Iris has the chance to step into the golden life she’s always envied—and get one step closer to the hundred-million-dollar inheritance left by her manipulative father. All Iris would need to do is ensure she’s the first of his seven children to fulfill the strange conditions of his will.

But Iris soon discovers that her twin was keeping more than one secret, and Iris’s life lurches between glamorous dream and paranoid nightmare. In a family in which the winner takes all, whom can she trust? And how far will she go to get the life she’s always dreamed about?
