Dillon's stirring, fiery debut pits a fearless nun's full-throated cri de cœur against the abuses of predator priests and domestic violence. In Bedford-Stuyvesant, Brooklyn, Mercy House offers shelter to battered women and girls. A 69-year-old nun named Sister Evelyn ("Evie") cares for them with two other older nuns, Sister Josephine and Sister Maria. Evie will stop at nothing to protect the sheltered women, and when an abuser shows up at Mercy House with a gun, Evie torches him with flame-lit Lysol. After a surprise visit from Bishop Hawkins, who had sexually assaulted Evie when she was a novitiate in the 1960s, she rightfully fears that he will try to use his authority to shut down Mercy House because of the Lysol incident and other infractions. Evie butts heads with Josephine over her decision to help a rape victim get an abortion, and receives censure from Hawkins for performing Reiki, lamenting how little she can do against a church that has always placed women below priests. Dillon balances her protagonist's righteous anger with an earnest exploration of Evie's faith and devotion to justice and community service. This uncompromising story will light up book clubs. (Feb.)
