"This is the best sort of fantasy imaginative, inventive, and believable. Harvey Potter is a wonder he's the owner of a genuine U.S. Government Inspected Balloon farm. And Nolen's tale about this man, narrated by the African-American girl who learns balloon-farming magic from him, is equally wondrous.... This title should sail onto every library shelf. May Nolen grow a bumper crop of books." School Library Journal.
"Downright glorious."Publishers Weekly(starred review).
