Novelist Homes's searing 2004 New Yorker essay about meeting her biological parents 31 years after they gave her up for adoption forms the first half of this much-anticipated memoir, but the rest of the book doesn't match its visceral power. The first part, distilled by more than a decade's reflection and written with haunting precision, recounts Homes's unfulfilling reunions with both parents in 1993 after her birth mother, Ellen Ballman, contacted her. Homes (This Book Will Change Your Life,) learns that Ballman became pregnant at age 22, after being seduced by Norman Hecht, the married owner of the shop where Ballman worked. But Ballman's emotional neediness and the more upwardly mobile Hecht's unwillingness to fully acknowledge Homes as a family member shakes Homes's deepest sense of self. The rest of the memoir is a more undigested account of how Ballman's death pushed Homes to research her genealogy.
