"If you always feel fully and completely happy, my friends, then you do not need my drops and I will not sell them to you for any amount of money." --Master Melville

Eleven-year-old juggling enthusiast Sullivan Mintz helps his family run the Stardust Home for Old People. It's not ideal: his best friend, Manny, is eighty-one years old. But life as usual turns upside down when Master Melville's Medicine Show comes to town. Sullivan's excitement at finding performers his own age dissolves into dread when he steps onstage for a magic act only to wake up imprisoned in the traveling show's caravan. As his fears subside, his questions multiply. Is his family better off without him? Would life as a juggler performing with other kids be worse than living in an old folks' home? Being kidnapped could be the best thing that ever happened to him . . . or decidedly not.
