The private thoughts of a teenage girl are often revealed only in the pages of her diary. When author Melanie Bellah's two daughters, Tammy and Abby, died as teenagers in unrelated incidents, Melanie and her two other daughters, Hally and Jennifer, lived through the confusing and tragic period in very different ways. While Melanie turned to her support system of friends and family, Hally and Jennifer turned to their diaries. Now in their forties and mothers themselves, Hally and Jennifer have shared the diaries the sisters kept as high school students with their mother. In "Abby and Her Sisters", Melanie weaves her own recollections together with the raw, honest words of her daughters, painting an astonishing portrait of four American teenagers growing up in the 1970s. Filled with courage, strength, and love, "Abby and Her Sisters" is a memoir of adversity and ultimately, survival.
