Hunter's life is at a turning point: After years of fighting his father for it, he's gotten top surgery. He's finally starting to feel comfortable in his own skin . . . only to be attacked by a strange creature in his backyard.

The encounter should kill him, but his best friend Gabe intervenes, and Hunter is able to walk away from the incident with his life--and new body--mostly intact. Still, something isn't right. First, his wounds are healing quickly--too quickly. Then there are the feverish nightmares, the sudden return of his period, and his teeth . . . they're falling out of his head.

Enter Mars, Hunter's other best friend. A horror movie devotee, Mars points out the obvious: That mysterious creature was a werewolf, and Hunter is becoming one too--unless they can figure out a cure, which basically means they have to kill the creature that bit him.

Now, Hunter, Gabe, and Mars are in a race against time. A voice that could only belong to the creature itself is worming its way into Hunter's head, and as the days pass, it's only getting louder. It promises revenge on Hunter's transphobic peers if he succumbs to his lycanthropic transformation. Or he can reject the monster and fight alongside his friends before the body--and life--he's fought so hard for slips away for good. The choice is Hunter's.
