What would you do if a bunch of letters jumped right off the page while you were reading a book? Run after them, of course. Join Sue MacDonald as she travels from a railroad station to a sewer to a mountain peak and more, all in an attempt to capture her renegade vowels. Reading a book has never been so interactive!

Jim Tobin's clever text—based on a favorite children's song—is perfectly coupled with Dave Coverly's winning illustrations. Get ready for a madcap adventure starring five very important letters.
