The Rabbits' Wedding
by Garth Williams
Two little rabbits, one white and the other black, played happily in the forest. But often, the little black rabbit looked very sad. Finally, he admitted that he was wishing that he could be with his friend forever and always.
"Why don't you wish a little harder?" said the little white rabbit. So the little black rabbit wished a little harder, and his wish came true.
Note: First published in 1958, this was once a controversial book. It was deemed unacceptable because it depicted a marriage between two animals of different colours.
