written by Josh Funk

George and Blaise are pen pals, and they write letters to each other about everything: their pets, birthdays, favorite sports, and science fair projects. There’s just one thing that the two friends don’t know: George is a human, while Blaise is a dragon! What will happen when these pen pals finally meet face-to-face?


A sweet and clever friendship story in rhyme, about looking past physical differences to appreciate the person (or dragon) underneath.
