They are three very different women: Zoe, the pretty blonde schoolteacher; Jenny, the former hand model turned model mother and wife; and Nadia, the free spirit who entertains at children’s parties. But when they are targeted by a sexual predator, they become sisters closer than kin. Suddenly they share the same dread when they approach their doorsteps, fall victim to the same rising panic as darkness falls. For someone is watching them, learning them better than they know themselves. And when the gruesome threats begin to escalate, each woman faces a horrifying truth: No one is coming to the rescue, not even the police. Stalked by an unknown killer, each can count only on herself, and do whatever it takes to survive.
