The brilliant and beloved gang from the New York Times bestselling series is back--and ready to face new threats, dangerous dilemmas, and irresistible adventures. 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. The Mysterious Benedict Society is a modern classic, drawing comparisons to J.K. Rowling and Roald Dahl, named a Time magazine "Best Young Adult Book of All Time," and selling over 3 million copies. In The Mysterious Benedict Society and the Riddle of Ages , 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.

Fans of the series will be thrilled to see the Society has grown up a little with them, while a new generation of readers will fall in love with this irresistible series.
