Jon Walker and Night Thomas lived their childhood in a cult. They embraced the lifestyle, and it was there that they were trained as BDSM Masters. Only when the cult was infiltrated by undercover agent Reilly did the boys learn of the cult’s seedy underside, and help to destroy it. Nearly fifteen years later, Jon’s job as a high school teacher—and his lust for the school’s gorgeous secretary, Carly—bring him close to the normal life he’s always craved. Just when that life is within his grasp, Reilly returns. An incarnation of the cult has resurfaced with Jon’s evil mother at the helm, and Reilly wants Jon and Night to go undercover to stop Cassandra Walker once and for all. Shocked by his mother’s return and his BDSM past come back to haunt him, Jon is terrified of Carly discovering his dark secrets. Including the darkest of all—his complex relationship with Night, and his unrelenting urge to share Carly with his best friend.
