Children, especially, little girls are drawn to tiny things. I wanted desperately to be Tinkerbell as a child and I've never really gotten over my own obsession (which is likely why I still like playmobil as a grown woman).
Anyway, in this story a sweet old childless couple miraculously find 12 teeny tiny babies after a magical moonlight rain shower. Without a second thought they begin to care for and protect the babies as their own. And that's all I'm going to tell you! It's a sweet story with great illustrations.
