Seeing as how he grew up with bookcases instead of walls, my son reads quite a bit. One series he loves and continues to reread often is the Bone books by Jeff Smith.
[He actually wrote Jeff Smith some fan mail and is eagerly waiting for a reply. I signed him up for the twice-monthly Letters in the Mail from The Rumpus, and he thinks that these are all letters from Jeff Smith’s friends.]
Here is a fan-fic comic he made about Bone (I’ve added some edits for clarity). Note that because he’s a boy, he’s included the obligatory fart joke.
