Julia has had enough of the sex noises her roommate makes; of her dead-end government job; of the one-night stand who accused her of breaking his penis. The only thing she hasn't had enough of is orgasms; she hasn't had proper sex in three years. At a warehouse party in a part of town where trendy people who have lots of sex go on a Friday night, she meets a conceptual artist, who also happens to be a woman. Julia's sexual awakening begins; her new lesbian life is exhilarating. She finds her tribe at queer swing dancing classes, and guided by her new lover Sam, she soon discovers London's gay bars, BDSM clubs, and the complexities of polyamory. Soon it becomes clear that Sam needs to call the shots, and liberation comes to bear a suspicious resemblance to entrapment. -- adapted from jacket
