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. 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 these irresistible adventures.
