I've read lots of books in my short 14 years, and not all of them were reccomendable, but these books are:
Monkeewrench
Ironman
Wildside
Where The Red Fern Grows
Define Normal
Cut
Jesus Freaks
The Bible
God's Words of Life For Teens
A Tale of Three Kings
I'll think of some more later, and eventually I'll have summaries up here..
