"Wednesday Wilson is in a major funk, and the only thing that can make this day worse is that funks are contagious--and hers is rubbing off on her brother, Mister. When Wednesday discovers that the true cause of Mister's funk is having to present his family tree at the school assembly, she devises a plan to get Mister a Worry Marble that will fix all his problems. And then a crowd of kids at recess also want Worry Marbles to fix their problems, and Wednesday finds herself back in business! There's just one problem left to fix: can Wednesday and her friends find enough marbles in time to keep their new business running? This second book in the Wednesday Wilson series is full of funny illustrations and footnotes to keep emerging readers engaged to the very last page."-- Provided by publisher
