The Strongest Girl in the World And, The Invisible BoyUnknown - 2007
Then there's Sam--poor Sam! When his parents take off for a trip to the moon, Sam is imprisoned by the wicked Hilda Hardbottom. He must find a way to escape, but how? Could his salvation come in the form of a small, splotchy alien? Maybe--if that alien has the power of invisibility, and the inclination to share!
In these two delightfully silly stories of extreme magic, enticingly packaged in a flip-book format, resourceful kids rely on their sense and savvy to save the day.
