Son of No One (Dark-Hunter #23) by Sherrilyn Kenyon

It’s not easy being life’s own personal joke, but Josette Landry has made an unstable peace with the beast. Life will continue to throw every bad thing it has at her, and she will continue to not put her head in an oven. But that’s okay. That which doesn’t kill her will just require a few hours of mental insanity.

Completely down on her luck, Josette takes a job with a local paranormal group trying to get their own cable show as a photographer and camerawoman. Yeah, they’re even crazier than she is. The only paranormal thing she believes in is the miracle that keeps her rusted out hoopty running. But when her group accidentally releases something truly evil into the world, they are forced to call in reinforcement.
