From the New York Times bestselling author of Something in the Water comes “an utter white-knuckle ride that took me into a heart of darkness” (Lucy Foley, author of The Paris Apartment).

“Addictive, thrilling, intoxicating.”—Lisa Jewell, author of None of This Is True

“The vacation home of dreams . . . or nightmares? What a ride—I tore through this nail-biting, pacey read.”—Sarah Pearse, author of The Retreat
Nina, still grieving from the loss of her father, discovers that she has inherited property in the British Virgin Islands—a vacation home she had no idea existed, until now. The house is extraordinary: state-of-the-art, all glass and marble. How did her sensible father come into enough money for this? Why did he keep it from her? And what else was he hiding?
Maria, once an ambitious medical student, is a nanny for the super-rich. The money’s better, and so are the destinations where her work takes her. Just one more gig, and she’ll be set. Finally, she’ll be secure. But when her wards never show, Maria begins to make herself at home, spending her days luxuriating by the pool and in the sauna. There’s just one rule: Don’t go in the basement. That room is off-limits. But her curiosity might just get the better of her. And soon, she’ll wish her only worry was not getting paid.
