Edge of Darkness (the Cincinnati Series Book 4)

Homicide detective Adam Kimble is no stranger to battling demons. But Meredith Fallon is a different kind of weakness: one that could actually be good for him, if only he would let himself depend on her. Meredith has loved Adam for a year, and seeing how hard he's worked to deal with his PTSD makes her feelings only stronger, but she respects his needs. Her work keeps her busy anyway: she counsels sexually abused women like Mallory Martin to help them reintegrate into the world. But someone doesn't want Meredith helping women like Mallory, and Meredith finds herself the target of a very determined killer. Adam would risk anything for Meredith, but they'll soon find out the killer is just a little too close to home...
