"No one does suburban paranoia like Shari Lapena." —Ruth Ware, internationally bestselling author of The Woman in Cabin 10

Maybe you don't know your neighbours as well as you thought you did . . .

In a quiet, leafy suburb in upstate New York, a teenager has been sneaking into houses—and into the owners' computers as well—learning their secrets, and maybe sharing some of them, too.
