Stuttering Darby is never perfect enough for her mother. Justin’s been silent since his dad died. Naz is struggling to learn English. But after they meet at Camp Inch, mysterious calliope music from an abandoned warehouse grants them power to communicate — without words. Why? When they sneak into the building to find out, it bursts into a magical carnival, and they’re greeted by the ghost of Leroy Usher, who can’t rest until his property brings joy to children. He asks for their help convincing his family to restore the carnival to its former glory. In return, he promises to teach Darby, Justin, and Naz how to find their voices. Mr. Usher sweeps them off on a series of adventures where they learn they’re capable of more than they ever imagined. Meanwhile, they scheme to persuade the Usher family to sell the carnival to Camp Inch. With each challenge, their confidence in communicating – and in themselves – grows. But when Darby’s bunkmates trick her into starring in the camp’s talent show, her budding confidence falters. Can she risk being less than perfect by performing in the show and speaking up to Mr. Usher’s resistant son? If not, she’ll put the carnival in danger and sabotage her most important quest: to believe in herself, stutter and all.
