I had this book as a child and loved it. I am so excited to pass it on to my kids. It is a realistic sibling story. Definitely a classic!
Harvey & his sister learn that being friends & cooperating is more fun than being exclusive & one-upping each other. A lovely book with typical Hoban animal drawings. (I think the animals are otters, but it's a little hard to tell. At any rate, they're cute!)
