The Great Garage Sale — Marilyn Helmer

With the help of his wild imagination and enthusiasm, DJ, the hero of Adventures at Camp Lots-o-Fun, deals with one disaster after another -- Super Stackers, "weeding" his mom's garden, facing Tiger the Terrible and a misspelled sign. But when DJ mistakenly sells the wrong box of jewelry to his new friend Sam at his grandma's garage sale, those disasters seem minor. Riding his beloved skateboard, Speedwell, DJ sets out to search for Sam, which is a challenge in itself. When he finally finds Sam, DJ is not prepared for the enormous sacrifice he will have to make to get the jewelry box back.
