Grief memoirs typically meditate on the loss of someone so close to the author that they could have listed the deceased as an emergency contact. Candace Jane Opper’s Certain and Impossible Events is not that kind of memoir. The book revolves around the death of a boy Opper wasn’t exactly close with—a crush whose phone number she memorized when she was thirteen. He died by suicide, at age fourteen, in 1994, eight days after Kurt Cobain’s body was found. More than twenty-five years later, Certain and Impossible Events is Opper’s attempt to map her ongoing obsession with the boy’s death.
