Are you a gifted child looking for special opportunities? When a peculiar advertisement appears in the newspaper for children to take part in a secret mission, children everywhere sit a series of mysterious tests. In the end, just four children succeed: Reynie, Kate, Sticky and Constance. They have three things in common: they are all honest, all remarkably talented and all orphans. They must go undercover at the Learning Institute for the Very Enlightened where the only rule is that there are no rules. There they must work as a team to save not only themselves, but also the world outside the walls. It should have been a celebration party, but now it's another mind-bending mission for the children of the Mysterious Benedict Society. Join Reynie, Kate, Sticky and Constance as they race across the globe by train, bicycle and ship to save their beloved Mr Benedict. It's a perilous journey that will test all their unusual talents. Reynie, Kate, Sticky and Constance are back-but so is Mr Curtain, with another devious scheme! Can the Mysterious Benedict Society thwart Mr Curtain's plans, even while held prisoner? Join them on their adventure as they face all sorts of dilemmas, in a bid to save Stonetown. 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.
