Ten Thumb Sam — Rachel Muller

Sam Stringbini, the youngest son in a family of circus performers, is living every kid's dream, except for the fact that he is no good on the high wire, trapezes freak him out and magic mystifies him. When the Triple Top Circus is threatened by repeated acts of sabotage, Sam is the number one suspect. To clear his name, Sam enlists the help of his cousin, Harriet, and discovers that, while he may never be a sword-swallower or a lion-tamer, he just might be able to save the circus.
