When Nina's father dies, she inherits a gleaming dream vacation home in a balmy tropical paradise - one she had no idea existed. The house is extraordinary: state-of-the-art, all glass and marble. How did her sensible father ever have enough money for this? And why not tell her about it? Desperate to uncover why he hid such a big secret, she decides to visit.

Maria, once an ambitious medical student, is now a nanny for the super-rich. The money's better, and so are the destinations - like this new assignment in the British Virgin Islands. But when her wards never show, Maria begins to make herself at home, spending her days luxuriating by the pool. There's just one rule: Don't go in the basement. But her curiosity might just get the better of her. And soon, she'll wish her only worry was not getting paid.
