Riku Onda (Japanese name: 恩田 陸), born in 1964, is the professional name of Nanae Kumagai. She has been writing fiction since 1991 and has won the Yoshikawa Eiji Prize for New Writers, the Japan Booksellers' Award, the Mystery Writers of Japan Award for Best Novel for The Aosawa Murders, the Yamamoto Shūgorō Prize, and the Naoki Prize. Her work has been adapted for film and television. The Aosawa Murders was her first crime novel and the first time she was translated into English. It was selected by The New York Times as a Notable Book of 2020.
What I like about this book is that the main character is 神原惠彌, who was also one of the main characters for Maze. This time, he goes into a city in Japan to bring back his twin sister, 和見. I would like to see more stories about 惠彌 and his adventures!
