When Simon Burns is fired from his job without warning, he takes on the role of stay-at-home dad for his three-year-old son. But his reluctance pushes his already strained marriage to the limit. In the nestled playgrounds of the Upper West Side, Simon harbors a simmering rage at his boss' betrayal. Things take a turn when he meets a tight-knit trio of dads at the playground. They are different from other men Simon has met, stronger and more confident, more at ease with the darker side of life- and soon Simon is lured into their mix. But after a guys' night out gets frighteningly out of hand, Simon feels himself sliding into a new nightmarish reality. As he experiences disturbing changes in his body and his perceptions, he starts to suspect that when the guys welcomed him to their "pack," they were talking about much more than male bonding. And as he falls prey to his basest instincts, Simon must accept that werewolves exist if he is to turn the tides of his fortune...

There were nights he made constant love to his wife, nights he roamed the city streets, nights he doesn’t even remember. And it’s one of those black-outs that’s going to come back to haunt him. For Simon isn’t the man he once was. In fact, he’s not really a man at all anymore. He’s a member of the pack. And once you’re in, it’s impossible to get out…
