ulia hasn’t had sex in three years. Her roommate has a boyfriend—and their sex noises are audible through the walls, maybe even throughout the neighborhood. Not to mention, she’s treading water in a dead-end job, her know-it-all therapist gives her advice she doesn’t ask for, and the men she is surrounded by are, to be polite, subpar. Enough is enough.

So when Julia gets invited to a warehouse party in a part of town where “trendy people who have lots of sex might go on a Friday night”—she readily accepts. Whom she meets there, however, is surprising: a conceptual artist, also a woman.

Julia’s sexual awakening begins; her new lesbian life, as she coins it, 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 and BDSM clubs, and . . . the complexities of polyamory. Soon it becomes clear that Sam needs to call the shots, and Julia’s newfound liberation comes to bear a suspicious resemblance to entrapment . . .

In at the Deep End is an unforgettably frank, funny, and racy odyssey through the pitfalls and seductions we encounter on the treacherous—and more often, absurd—path to love and self.
