I Know This Much Is True - Chapters 13 - 14

Dominick remembers Ralph Drinkwater's twin sister Penny. She was abducted and murdered by the edge of the Falls.  Dominick felt guilty because the day before she died he had lied and said that Penny had stolen Oreo cookies, and got her in trouble with the principal. In Chapter 14, Dominick remembers the baby that he and Dessa lost when she was three weeks old. Angela died of SIDS. It ended up being the cause of their marriage failing because of Dominick's failure to express his feelings over her death.
