In a beachfront mansion in Martha's Vineyard, Annick and Rebecca relax, safe in the knowledge that their young children are in the care of life-long friend Tash. But by the end of the afternoon, one of the children will have vanished...

Annick, daughter of an actress and an assassinated president, has spent her life running from the truth of her family's wealth.

Rebecca has always done the right thing. Perfect daughter. Perfect wife. Perfect mother. She's beginning to wonder if she'll ever get chance to live for herself.

And Tash, free from the poverty of her heritage, has the world at her feet. So why is she struggling to keep a grip on her life?

This is the sweeping story of three very different women; their pasts, their secrets, and their friendship.
