Wallace Lake, Ohio, takes care of their own. Unwelcoming of outsiders, the community closes ranks when four women are found murdered along the water's edge. Agent Luce Hansen of the Ohio Bureau of Criminal Investigation must find a way in before another woman loses her life to the ruthless serial killer. With the help of her new team—a hot rookie and a smart, beautiful medical examiner—Luce uncovers a ring of devotion surrounding the prime suspect. As Luce works to unearth the dark secrets of this close-knit town, she learns to what extraordinary lengths people will go to protect the ones they love. And when Luce feels forsaken, both professionally and personally, she must regain trust in her most valuable investigative tool: herself.
