I Left My Back Door Open

""I am not young, or thin, or white, or beautiful,'' says the narrator of Sinclair's worldly-wise and entertaining new novel. Gun-shy after several catastrophic relationships, Chicago deejay Daphne (Dee Dee) Dupree is an outwardly successful African-American woman aching for self-realization. Sassy from the safety of her broadcasting booth, the heavy-set 41-year-old jauntily offers her weight as the cause of a recent breakup (""The brotha didn't 'preciate my meat""). In reality, Dee Dee struggles with the shame of being fat and bulimic. She yearns for mature love and the self-confidence she's sure will accompany finding the right man. Meanwhile, relationships she's relied on as stable fall into flux: the 20-year marriage of her high school friends Sarita and Phil is falling apart; her best friend, Sharon, has come bursting out of the closet, an enthusiastic lesbian at 40; Jade, her belly-dancing instructor and fellow deejay, is on the cusp of ending an unhappy marriage. Dee Dee's only constant is her cat, Langston. The mixed blessing of a sexual harassment suit at work brings union mediator Skylar into her life. Attraction notwithstanding, their romance is tentative and obstructed; his (white) ex-wife is trying to reconcile with him and his eight-year-old daughter relentlessly blocks her father's new interest. In the course of sorting all this out, Dee Dee takes stock and faces some long repressed childhood memories. Refreshingly upbeat and robustly spiritual, the novel steers clear of sentimental inspirational writing by means of its frank and funny dialogue, and follows Sinclair's (Coffee Will Make You Black; Ain't Gonna Be the Same Fool Twice) earlier successes admirably.
