Bitter Falls — Rachel Caine

She's investigating a cold case no one else could -- by going places no else would dare.

In spite of a harrowing past still haunting her, Gwen Proctor is trying to move forward. Until a new assignment gives her purpose: the cold-case disappearance of a young man in Tennessee. Three years missing, no clues. Just Ruth Landry, a tortured mother in limbo. Gwen understands what it's like to worry about your children.

Gwen's investigation unearths new suspects…and victims. As she follows each sinister lead, the implications of the mystery grow more disturbing. Because the closer Gwen gets, the closer she is to a threat that looms back home.

In a town that's closed its ranks against Gwen; her partner, Sam; and her kids, there's no bolder enemy than the Belldene family -- paramilitary, criminal, powerful, and vengeful. As personal vendettas collide with Gwen's investigation, she's prepared to fight both battles. But is she prepared for the toll it could take on everyone she loves?
