As our hero struggles to reach the city of Solla Sollew, where they never have troubles, at least very few, we realise that it's better to face up to life's problems than to try to run away from them!

With his unique combination of hilarious stories, zany pictures and riotous rhymes, Dr. Seuss has been delighting young children and helping them learn to read for over fifty years. Creator of the wonderfully anarchic Cat in the Hat, and ranked among the UK's top ten favourite children's authors, Dr. Seuss is a global best-seller, with over 650 million books sold worldwide.

As part of a major rebrand programme, HarperCollins is relaunching Dr. Seuss's best-selling books. In response to consumer demand, bright new cover designs incorporate much-needed guidance on reading levels. The standard paperbacks divide into three reading strands - Blue Back Books for parents to share with young children, Green Back Books for budding readers to tackle on their own, and Yellow Back Books for older, more fluent readers to enjoy. This is a Yellow Back book.
