from the back cover:

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?
