A newlywed woman faces frosty neighbors as a coldblooded killer stalks Seattle in the New York Times bestselling author's chilling domestic thriller.

The houses in Willow Tree Court are sleek and modern—the kind designed to harbor happy families and laughing children. No one would guess the secrets that lurk beyond the neat lawns and beautiful facades.

Molly Dennehy is trying to fit in to her new surroundings, though her neighbors are clearly loyal to her husband's ex-wife. But that's the least of Molly's worries. Her stepson's school has been rocked by a brutal slaying, and a psychopath known as the Cul-de-Sac Killer is murdering families in Seattle homes. Homes just like Molly's.

With each passing day, Molly grows more convinced that someone is watching her family, someone consumed with rage and vengeance. On this quiet road, a nightmare has been unleashed, and the trail of terror will lead right to her door . . .
