When they were girls, Sae, Maki, Akiko and Yuko were tricked into leaving their friend Emily with a mysterious stranger. Then the unthinkable occurred: Emily was found murdered hours later. The four friends were never able to describe the stranger to the police; the killer's trail went cold. Asako, the bereaved mother, curses the surviving girls, vowing that they will be the ones to pay for her daughter's murder . . . Like Confessions, Kanae Minato's award-winning, internationally bestselling debut, Penance is a dark tale of revenge and psychological drama that will leave readers breathless.
