No Man Standing — Barbara Seranella

Against the odds, Munch Mancini pulled herself out of a dead-end life of drugs and booze, transforming into a high-class mechanic, the owner of a fledgling limo business, and a good mother to her daughter. But she hasn't forgotten her old friend Ellen Summers. Munch and Ellen were young and foolish together. But where Munch went straight, Ellen went to prison. Now, one day before her release, someone murders Ellen's mother and stepfather--and the killer is convinced Ellen has something he wants.

Alone and frightened, she runs to Munch for help. Though Ellen's story doesn't add up, the danger proves to be most definitely real. Unwilling to trust the police for fear of sending Ellen back to prison, Munch embarks on a mission to find the killer and get her friend out of trouble one last time--before trouble comes looking for her.
