Christina and Rosie are sisters who are always kind to animals. They put up houses for birds and leave nuts out for chipmunks. In springtime, they learn about monarch butterflies and how the plants they need are dwindling. They decide to plant a little garden to provide pollen for the monarchs and milkweed for the caterpillars. Meanwhile, they notice an injured squirrel. But, when they try to get close to see how they can help, they realize he's scared of them because they are so much bigger than he is. They make a wish to become fairies...and it comes true! They are able to help the squirrel! After turning back into little girls, they contemplate why this wish came true when previous wishes did not. They realize that this wish came true because it was for helping someone else. As they are starting to go inside after their incredible day, they notice the sky is full of monarch butterflies! The monarchs had found the new garden! The girls realize they don't have to be fairies to make a difference.

This is a sweet, rhyming story that encourages children to be kind. It demonstrates how even a small action can have a big impact!
