What are Your Ten Best-Ever Teen Books?

This one's for book lovers, especially those who like to read in the YA genre.  After collecting nominations for a top-100 list of the best young adjust books, NPR has come up with a list of 235 titles, and it's now up to the public to vote.  We can each pick 10 books from the list.

That's right 10 books.  I don't know how it will be/was for you, but it was incredibly difficult for me!

My votes were for:

1. Anne of Green Gables (series) by Lucy Maud Montgomery
2. The Dark is Rising (series) by Susan Cooper
3. Harry Potter (series) by J.K. Rowling
4. His Dark Materials (series) by Philip Pullman
5. The Hunger Games (series) by Suzanne Collins
6. The Princess Bride by William Golman
7. The Shiver Trilogy (series by Maggie Stiefvater)
8. To Kill a Mockingbird by Harper Lee
9. Twilight (series) by Stephenie Meyer
10. Tuck Everlasting by Natalie Babbitt

But, I also wanted to vote for:

1. Betsy-Tacy Books (series) by Maud Hart-Lovelace
2. Flowers for Algernon by Daniel Keyes
3. Howl's Moving Castle by Diana Wynne Jones
4. The Mortal Instruments (series) by Cassandra Clare
5. The Outsiders by S.E. Hinton
6. A Separate Peace by John Knowles
7. Speak by Laurie Halse Anderson

And where in world was A Wrinkle in Time?  I don't get why it's not on the list when the Betsy-Tacy books are there; I could have sworn those were little kids.  But then again, NPR does talk about the debates they went through trying to figure out just what fits into YA.  At any rate, I can't wait to see the final list.  I just may have to re-read some of these titles.
