“I never intended this book to be published,” writes Phoebe Gloeckner in the introduction to her new collection, A Child’s Lifeand Other Stories. Perusing these finely drawn, mostly autobiographical comic works, which span twenty years, it’s not difficult to see why its creator might be wary of foisting her stories on a public whose idea of an enjoyable narrative is Titanic. Gloeckner’s unsparing memory and painstakingly detailed pen-and-ink drawings of family dysfunction, childhood cruelty, and queasy sex make for seriously disquieting reading. The book takes us through the years with Gloeckner’s alter ego Minnie, whose childhood is dominated by her overbearing, ogling stepfather and whose adolescence is spent on the streets of San Francisco in a morass of unsavory drugs and even less savory men.
