A hyper-intelligent stalker attacks behavioral analyst and forensic psychologist Dr. Tori Crew at knifepoint, shattering the fierce independence she’s built since her parents’ unsolved murder. Forced into an off-the-books criminal investigation, Tori must push her expertise—and her fiercely guarded heart—to the breaking point as a killer’s pattern emerges.

Homicide Detective Blade St. James has been Tori’s friend and protector since childhood. Haunted by his own past of parental abandonment, Blade is determined to build a stable life and find the peace that always seems just out of reach.

But when Tori’s life is threatened, his protective instincts shift into overdrive. As they are plunged deep into a conspiracy with roots in her past, the boundary of their friendship blurs as danger closes in and their hearts reveal a truth they can no longer deny.

Can they unmask the sophisticated serial killer before they become the final, fatal piece in the pattern?
