Iris and Summer are identical twins, but beneath their striking resemblance lies a darkness that separates them. Insecure and cynical, Iris has always envied Summer’s charmed life—especially her perfect husband, Adam. When Iris is called to Thailand to help sail the family yacht, she sees an opportunity to change everything.
But when Iris finds herself alone in the middle of the Indian Ocean, everything shifts. Upon reaching land, Adam mistakes her for Summer—and Iris doesn’t correct him. With her sister gone, Iris steps into Summer’s life, complete with wealth, glamour, and a hundred-million-dollar inheritance at stake.
As Iris teeters between her dream life and a growing paranoia, one question remains: what really happened to Summer on that yacht?
Only Iris knows, and she’ll do whatever it takes to keep it that way.
