And of course, I'll always recommend the classics, like Anne of Green Gables, Little Women, What Katy Did (recently Nina held a book club for it), and it's really a fantastic story. 

Cappie thinks I have an MBA.

I would like to recommend classics, just as BHR recommended. Most of them have very high reading levels. I recommend Pufifn Classics books because not only do they publish the story, they also have a behind the scenes guide at the end of the book with a character guide, author biographies, book sneak peeks, and more.

I would recommend The Book Thief and I Am The Messenger, both by Markus Zusak. The Perks of Being a Wallflower is lovely. Or The Count of Monte Cristo perhaps? Do you like Classics or more modern books? 

Kingdom Keepers, Chasing Vermeer, Wendy Mass books, Mother-Daughter Book Club, The Red Blazer Girls

John Green

Maureen Johnson

Libba Bray

L. A. Meyer

I'm really sorry, but I don't have any good recommendations for you, but I'd also recommend John Green. The Book Thief is excellent, although it might make you cry. 

Thanks you guys. I went to the school's library yesterday and pulled out every single one of these books, even the ones I have already read. I've made  through two of them and I am just starting The Book Thief.
