When Horton the Elephant hears a tiny voice calling for help from a speck of dust, he is determined to save his new friend.

'A person's a person, no matter how small..'

Horton the elephant sets out to save the inhabitants of a speck of dust, in this classic and hilarious tale about friendship and respect, from the inimitable Dr. Seuss.

As part of a major rebrand programme, HarperCollins is relaunching Dr. Seuss's bestselling books, including such perennial favourites as The Cat in the Hat, Green Eggs and Ham and Fox in Socks. In response to consumer demand, the bright new cover designs incorporate much needed guidance on reading levels, with the standard paperbacks divided 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. Horton Hears a Who! belongs to the Yellow Back Books range.
