Into the Night

Into the Night - Cynthia Eden
Macey was the only survivor of "The Doctor." She was a doctor turned FBI agent to hunt killers. Bowen's girlfriend was the victim of a serial killer. He found, hunted that killer, and saved the next victim. He is now also part of the same FBI profiling task force. 
There is a serial killer hunting serial killers (with collateral damage). Macey and Bowen are tasked with hunting the killer down. I liked how everything was linked together and the conclusion; it wasn't a simple who-done-it. I did feel like the FBI *should* have caught on earlier then they did. Macey and Bowen are both likable and each have their issues. Said issues aren't quite overcome, but understand/accepted with communication.
