John Fredericks has been writing and drawing since he could hold a pencil. (His mom's still mad about that wallpaper in Pottsville.) Also, he’s the illustrator of the PRINCIPAL SAM series of children’s books, also available through Ravenswood. He works as a teacher, and lives with his family in Pennsylvania. You can follow him on Twitter @sketchingjohn and www.sketchingjohn.weebly.com.
