hen a spaceship lands in a nearby Dutch Woods, juvenile delinquent Jack Creedle and prim A-student Isadora Shumway form an unexpected friendship. Jack's uncle, Bud, a witty amateur inventor with unschooled Einstein abilities, has built a space-travel machine, and a group of hilariously bizarre space aliens are here to steal it. Despite themselves, the Skreeps manage to capture and fly away with Jack, Isadora, and Uncle Bud—and three other ooman bings from Uurth. Come along on a wild space voyage as our unlikely heroes try to outwit an entertaining cast of aliens who are determined to conquer Planet Earth.
