  • You want a thriller that wraps everything up neatly. This one trades clean resolution for messy, complicated answers.

About this book

Former homicide detective Nicole Foster has lost everything. Forced off the police force by her corrupt partner and lover, she is broke and battling a gambling addiction. Her only prospects are a bed at a homeless shelter and painful memories of three-year-old Kelsey Chase, whose unsolved murder ended her career. Reexamining the old case, Nicole becomes convinced something was wrong with the investigation: the mother seemed indifferent, a pedophile's suicide appeared convenient, and critical questions remained unanswered. When Kelsey's grieving father asks for her help, Nicole returns to the case, hoping to find redemption. As her investigation deepens, Nicole uncovers layers of wrongdoing and personal betrayals. A shocking discovery may finally bring justice for Kelsey and offer Nicole a chance to rebuild her life.
