A Sydney detective’s dark past comes to light in this “nail-biting . . . riveting thriller” by the #1 New York Times bestselling crime author(Publishers Weekly, starred review).

Frank’s job is to keep an eye on his partner while she's there—but is it for Eden's protection, or to protect others from her? Walking a tightrope between duty and desperation, Frank confronts a threat from Eden’s past. Suddenly, the hunter is the hunted. And a killer’s vicious desires are about to be unleashed…

“Grim, gritty, fast-paced …each character adds depth and interest to an already absorbing plotline. Fox fantastically builds on her previous book, leaving a cliff-hanger that will leave readers clamoring for the next series title.” —Library Journal (Starred Review)
