Frog is worried about his health: His heart is beating too fast. His friend Hare says that he must be in love- but who is he in love with? This important book deals not only with the nature of being in love but also the issue of prejudice: ' A frog can't be in love with a duck. You're green and she's white. ' But Frog doesn't let that bother him . . . Green and white. Love knows no boundaries. This enchanting love story was the first book by Max Velthuijs on the Andersen list - now available as an Andersen paperback.
