The brilliant and beloved gang from the New York Times best selling series is back! Since The Mysterious Benedict Society debuted twelve years ago, the series has become a modern classic, drawing comparisons to J.K. Rowling and Roald Dahl and selling over three million copies. Some time has passed since the inimitable quartet of Reynie, Sticky, Kate, and Constance have had a mission together. 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 villainous Mr. Curtain and a telepathic enemy tracking their every move, not to mention a dramatically preteen Constance. In its triumphant return, the Society encounters all new challenges, but the series' trademark sly humor, sweet camaraderie, hairsbreadth escapes, and mind-bending puzzles are all as engaging as ever.
