Julia and Christopher Hygate have the picture-perfect life: gobs of money thanks to their lucrative shipping enterprise and an estate on a secluded island. When they meet Eve Sylvester, they know she is the exact person they should hire to be their child's nanny. Eve doesn’t have any living relatives, she’s lost touch with her friends, and her partner is out of the picture. Best of all, she’s expecting a baby. Eve thinks she’s landed the greatest gig. But the job seems too good to be true. Why would the Hygates hire Eve if she has no prior nannying experience? Why must Eve stay out of sight? And what’s with the mysterious yachts coming in and out of the Hygates' private marina? It's too late to ask questions, though. Eve is already in far too deep.

Cynical and insecure, Iris has long been envious of her twin sister 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 her life lurches between glamorous dream and paranoid nightmare.
