Wolf Cycle / Nick Lupo Series by W.D. Gagliani

It takes a beast to catch a beast. Nick Lupo is a good cop -- a bit of a renegade at times, with the instincts of a great detective... or maybe a wolf. Lupo has a lot in common with wolves, which is only natural considering he’s a werewolf. He’s battled the creature inside him for years, but now there’s another predator in the area. A bloodthirsty serial killer is leaving a trail of victims, and it’s up to Lupo to track him down and stop the slaughter... moreIt takes a beast to catch a beast.

There's something terrible happening near the resort town of Eagle River, Wisconsin. Some people are afraid there's a wild animal on the loose, savagely tearing its victims apart. Others, like Nick Lupo, know better. Lupo knows a werewolf attack when he sees one.

He's also a homicide cop, so it may be up to him to hunt down one of his own kind... moreThere's something terrible happening near the resort town of Eagle River, Wisconsin.
