Book Recommendations?

I am interested in hearing if anybody would like to contribute their favourite children's (environmental) books -- if I ever have a spare moment, I always enjoy discovering new children's literature as well as following up on recommendations.

One of the most recent books for older children that I have read is the coming-of-age novel Replay by Sharon Creech, author of Walk Two Moons. The main character is Leo, a 13 year old, who dreams of acting, and who struggles to establish his own identity (especially in his large family). Although I occasionally found Leo's dreamy flashbacks a little confusing, I thought that the novel was well-written as a whole. I found it especially funny that Leo, who dreams of being a star actor, is cast in a bit part in his class play -- as an old crone!! If you ever have time, or, if you're like me and need a little light reading after doing homework, this book is definitely worth it!
