Another thought: have you looked books up on this site?

Find-a-book here: http://www.lexile.com/findabook/StudentInfo.aspx

I don't know if I'm ahead or behind the curve on Lexiles as a measure of how challenging a book is to read, so I won't explain it here. If you don't know what the heck they are, let me know and I'll be happy to explain. But it might help you find some books that are both interesting and not too challenging.
