Give and Take — Donna Jo Napoli

The Little Angel of Generosity loves giving gifts to his friends, especially when he gets a gift in return. And he loves helping children, as long as he earns another feather for his wings. He's still learning what giving is all about when he meets a little girl named Dinah who needs his help.
Dinah likes to give gifts, too. And she really likes to get nice things for herself. But her family doesn't have a lot of money, and she wants things they can't afford -- sometimes she even wants those things badly enough to take what doesn't belong to her. It's up to the Little Angel of Generosity to show her that it's not what you have, but what you give that counts.
