Ever since Mac's best friend, Amy, was murdered, Hemlock has been a dangerous place. But now that Mac, her boyfriend, Kyle, and Amy's ex, Jason, have investigated a mass breakout from Thornhill, a werewolf "rehabilitation" camp, the danger has only grown. Fear of the infection spreading is now at an all-time high, and anyone with a scar is suspected of being a wolf.
What makes Mac even more afraid, though, are the dark experiments that the warden of Thornhill was performing on wolves in a secret asylum called Willowgrove. Uncovering the truth about what happened may be the only way for Mac to save everyone she loves and end her nightmares for good.
