When they were children, Sae, Maki, Akiko and Yuko were tricked into separating from their friend Emili by a mysterious stranger. Then the unthinkable occurs: Emili is found murdered hours later. Sae, Maki, Akiko and Yuko weren't able to accurately describe the stranger's appearance to the police after the Emili's body was discovered. Asako, Emili's mother, curses the surviving girls, vowing that they will pay for her daughter's murder. Like Confessions, Kanae Minato's award-winning, internationally bestselling debut novel, Penance is a dark and voice-driven tale of revenge and psychological trauma that will leave listeners breathless.
