It takes a beast to catch a killer!

Nick Lupo is a good cop—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 gruesome trail of victims, and it’s up to Lupo to track him down and stop the slaughter. Will Lupo dare to unleash one beast to stop another?

Can one werewolf stop a pack of super-wolves?

Nick Lupo is a homicide cop with a difference. He's a werewolf. He's worked hard to control his condition, but it isn't easy to contain the beast inside him. It also means he has some very powerful enemies. Wolfpaw Security Services is a mercenary organization that wants Lupo dead. They want to infiltrate the US military with their own werewolves and they can't let anyone-especially a fellow-werewolf like Lupo-stand in their way.

Wolfpaw's genetic experiments have created a "super-wolf" nearly invulnerable to silver, and soon their ranks will be filled with these invincible warriors. Can one wolf-even a fierce beast like Lupo-face the fangs and claws of a pack of these killers and hope to survive?
