Over the Flames by Nichole Severn

When Arden Olsen discovers her mentor’s smoldering remains, she’s determined to expose the killer. Her work is the only way to process the grief tearing her apart. But the FBI’s lead case agent will do whatever it takes to keep her from getting involved.

Violent Crimes Agent Lawson Mitchell has been burned before—by the media and by Arden. She’s not going to let the story go, so as the killer escalates, keeping his ex-wife close is the only way to keep her safe. Even at the risk of losing his heart all over again.

As one of the most vicious serial offenders closes in, Lawson and Arden must confront the guilt and resentment they’ve harbored for one another and work together. Before there’s nothing left.
