Once upon a time not long ago, two responsible college professors, Lynn the psychologist and Kathy the literary scholar, fell in love with the television show Supernatural and turned their oh-so-practical lives upside down. Plunging headlong into the hidden realms of fandom, they scoured the Internet for pictures of stars Jensen Ackles and Jared Padalecki and secretly penned racy fan fiction. And then they hit the road—crisscrossing the country, racking up frequent flyer miles with alarming ease, standing in convention lines at 4 A.M.

They had white-knuckled encounters with overly zealous security guards one year and smiling invitations to the Supernatural set the next. Actors stripping in their trailers, fangirls sneaking onto film sets; drunken confessions, squeals of joy, tears of despair; wallets emptied and responsibilities left behind; intrigue and ecstasy and crushing disappointment—it’s all here.

And yet even as they revelled in their fandom, the authors were asking themselves whether it’s okay to be a fan, especially for grown women with careers and kids. “Crazystalkerchicks”—that’s what they heard from Supernatural crew members, security guards, airport immigration officials, even sometimes their fellow fans. But what Kathy and Lynn found was that most fans were very much like themselves: smart, capable women looking for something of their own that engages their brains and their libidos.

Fangasm pulls back the curtain on the secret worlds of fans and famous alike, revealing Supernatural behind the scenes and discovering just how much the cast and crew know about what the fans are up to. Anyone who’s been tempted to throw off the constraints of respectability and indulge a secret passion—or hit the road with a best friend—will want to come along.
