Leopold is just like every other boy in town...except that he can turn himself invisible! Perhaps when he grows up, Leopold will use his powers to fight the forces of evil...but for now, he just wants to have a little fun—sometimes at his sister's expense, other times as her partner in crime. Join Leopold and Celine as they turn everyday life into a silly adventure! by Michel-Yves Schmitt (Author), Vincent Caut (Illustrator).
