Out for Blood: A Serial Killer Crime Novel:

It's been six years since ex-cop Logan Fox lost his family, and their killer still roams free. Now working as a private investigator, Logan seeks justice on behalf of those around him. For those unable to protect themselves. For people like Jenny. When his only friend goes missing, Logan is horrified to find the link to a series of brutal murders in the area. But as he edges closer to the truth, he finds there's more to the kidnapping than first appears, and that the killer is linked to his dark past. A past he'd left behind long ago.
