I think that kids are a wonderful, wonderful reader to have in your head.
I never had a favourite book! I liked all kinds of things - science fiction, so I read Heinlen and Ray Bradbury, and I also liked reading about kids like myself, so I read Judy Blume and Norma Klein and Paula Danzinger and a lot of other writers. I also read James Herriot!
We're allowed as adults to create a life that we like. Kids don't have that freedom.
'Middle school' is used as shorthand for a time when things change. It's a time a lot of kids feel like they don't even have one good friend.
My kids really like food, and they like to cook, so it's a lot of fun to shop with them.
