Some people just won't take the hint when it's time to go to bed, but Marvin K. Mooney eventually gets the message! This fun tale by Dr. Seuss will delight young readers and remind them that they sometimes have to do what they are told! This delightful book forms part of the second stage in HarperCollins' major Dr. Seuss rebrand programme. With the relaunch of 10 more titles in August 2003, such all-time favourites as How the Grinch Stole Christmas!, Mr. Brown Can Moo! Can You? and Dr. Seuss' Sleep Book boast bright new covers that incorporate much needed guidance on reading levels: Blue Back Books are for parents to share with young children, Green Back Books are for budding readers to tackle on their own, and Yellow Back Books are for older, more fluent readers to enjoy.
