The Mysterious Benedict Society and the Riddle of Ages

After starring in three adventures, the inimitable quartet of Reynie, Sticky, Kate, and Constance haven't had a mission together in some time. But with the arrival of a new Society member—and a new threat—they must reunite to face dilemmas more dangerous than ever before, including the return of the villainous Mr. Curtain and his Ten Men, and a formidable enemy with a mystifying ability to track their every move.

In its triumphant return, the Society encounters all-new challenges, but the series' trademark sly humor, sweet camaraderie, hairbreadth escapes, and perplexing puzzles are all as engaging as ever.

The brilliant and beloved Society is back! But is it too late?
