Raw sex, real witchcraft, fast bikes, and ultraviolence… Chastity "Chass" Brunson, vice-president of the Coven Thirteen Motorcycle Club, is in a bind. Her MC, which was once at the very top of the Las Vegas underworld, has struggled in recent years due to its lack of a crucial thirteenth member. That may soon change, as the club has a few new business opportunities and a prospect member very close to attaining her “full patch.” Chass must juggle an affair with the prez of another MC, a flirtatious member of her own club, rival criminals encroaching on Coven Thirteen’s turf, and a deadly and mysterious prophesy told by the club’s oracle member, all while attempting to bring her club back to its rightful place at the top.
