A Virginia detective’s estranged wife is targeted by an obsessive killer in this psychological thriller by the New York Times bestselling author.

The first kill was easy. The second much easier. No guilt, no remorse, just a rush of adrenaline surging through him as each life drains away, and the pleasure of knowing their deaths help his beloved Lindsay. And there are so many more who deserve to die . . .

Lindsay O’Neil’s secret past is suddenly coming back with a vengeance. When she receives a twisted gift hidden in a bouquet of flowers, the detective assigned to the case is also her estranged husband. Only Zack knows the dark secret she lives with—or so she thinks. Now nothing can prepare her for the nightmare to come. Because everything Lindsay’s stalker does is for her. And spurning his gifts will only unleash the rage of a madman who’s far closer than she imagines . . .

Ten years ago, fifteen-year-old Scarlett Crosby was held captive in a terrifying ordeal with a girl named Della. Scarlett escaped, their predator was killed, and Della simply vanished. Detective Kevin Dawson always wondered if Della even existed.

A decade later, Scarlett is a successful artist. As hard as she tries to move on, the mysterious Della remains her inescapable obsession. Then a girl's body is discovered—a link to Scarlett's horrific past—and all her old traumas resurface. So does Della. Scarlett has seen her hiding in plain sight. The girl who knows Scarlett's secrets, who understands the desperate compromises Scarlett made to endure hell, and who, like Scarlett, embraced the darkness to survive.

As a suspicious Detective Dawson once again comes calling, and obsessions turn deadly, Scarlett fears there isn't a living soul she can trust. As for Della, who's watching from afar, what could she possibly want from Scarlett now? And what new nightmare lies ahead?
