As if being small and having S. Horten as his name isn't bad enough, now 10-year-old Stuart is forced to move far away from all his friends. But on his very first day in his new home, Stuart's swept up in an extraordinary adventure: the quest to find his great-uncle Tony—a famous magician who literally disappeared off the face of the earth—and Tony's marvelous, long-lost workshop.

Along the way, Stuart reluctantly accepts help from the annoying triplets next door… and encounters trouble from another magician who's also desperate to get hold of Tony's treasures.

“This is a romp of a story, and at the same time brainy and smart. I can't wait for the sequel."

—Kathi Appelt,
Newberry Honor Medalist

“I love Stuart’s Dad the best. His vocabulary was hilarious and made reading Horten’s Miraculous Mechanisms so fun!”

—Emily B., age 11
