Jonah and I are members of our own little Young Adult book club. I just finished The Last Olympian (Percy Jackson & the Olympians, Book 5) and he's gone back to reread the first in the series, Percy Jackson and the Olympians: The Lightening Thief.  Jonah, a huge Rick Riordan fan, also read The Red Pyramid (The Kane Chronicles, Book 1).

I just ordered Percy Jackson and the Olympians: The Ultimate Guide for him, but we need more books for him, so I turned to my sister in law for help. Tammy is a middle school languages arts teacher; it's very nice to have an in-house expert. She suggested the YA books:

1. The Mysterious Benedict Society
2. The Alex Rider Collection
3. Maniac Magee (My MIL, the former school librarian, bought this for Jo over the summer. Jo loved it.)
4. Evil Genius
5. The Bartimaeus Trilogy Boxed Set
