Instant #1 International Bestseller

"Cue greed, lust, secrets, and serious suspense. Count us in."--theSkimm

An insanely plotted book...riveting.--The New York Times Book Review

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?

Ferociously entertaining. A novel like a triathlon: part evil-twin thriller, part howdunit (or did-she-do-it?), part juicy family drama. Drop Knives Out and Double Indemnity into the blender, shake some Dead Calm over the froth, power it on, and you've got a cocktail like The Girl in the Mirror--fresh, flavorful, and utterly intoxicating. --AJ Finn, #1 New York Times bestselling author of The Woman in the Window
