Mysterious Benedict Society and the Riddle of Ages
The Mysterious Benedict Society and the Riddle of Ages is the fourth novel in Trenton Lee Stewart's middle-grade series about a team of gifted children recruited to solve puzzles and foil a villain. It reunites Reynie, Kate, Sticky, and Constance, now older, as they face a new threat tied to their old adversary and a mysterious newcomer. Like the earlier books it turns on riddles, codes, and teamwork, rewarding readers who enjoy working the puzzles alongside the characters. Published in 2019, it works best for readers who have followed the group from the first book rather than starting here.
