Emmy and the Plastic Pond — Nick Garlick

Emmy is sad. She's sad about the dirty, neglected pond at the bottom of her street. Can she clean it up? The strange and mysterious Ariel thinks she can. And says she should. So, with the help of her friends, Emmy sets to work. It isn't easy. Obstacles pile up. But she doesn't give in. She won't give in. The fate of the pond, and Ariel, depend upon it.
