Nellie is a marionette cat and she loves to dance. She's happy living with the old woman and the visits from Big Tom. She learns a lot about friendship, being on her own and how the moonshine is magical.
I think Natalie Babbitt is a very good writer; even her picture books are great. It's a very nice story about a wooden cat called Nellie and I just felt it was a very hopeful story. Someone you love and care about may be gone, but you'll always have your memories of them. And just because they are gone doesn't mean you stop living. I think this story does a good job of telling that.
Oh, and just believing in magical things. For Nellie and Big Tom, the moonshine was magical.
