Anyone have suggestions for a 10 year old who likes comic mischief? He's a huge fan of diary of a wimpy kid series but his reading level has moved beyond that. He's also really enjoyed the wild robot series, Matilda, and the skunk and fox books.
Thanks in advance!
Edit: thank you all for your great recommendations. I'm going to check them all out with him tonight!
