For Jacks Dowd, a college senior who feels ungrounded from his family and life in general, an alcohol and sex-infused weekend in Montréal sounds like a pretty good escape. His Spring Break binge takes a detour when he meets Benoit, an admiring drifter with startling green eyes. A hook-up turns into a day, two days, and then a full week in Benoit's hostel, making love and scarfing down take-out food. But at the end of the week, Benoit demands that Jacks make an impossible choice: stay with him forever, or go back to college and never see him again.

There's something dangerous about Benoit, but Jacks has fallen for him brutally. The night before Jacks is supposed to return to college, he finds Benoit in Mont Royal Park, where they first met, to try to work things out. Benoit springs on Jacks an unfathomable secret: he's a mythical creature, half man and half jungle panther. He traps Jacks in an abandoned cabin and performs an occult rite so they will be mated forever.

Jacks must learn how he can fit into the bizarre and violent world that is now his.
