While it's not my favorite, I recently read "The Lightning Stenography Device" and one of the characters has his persona played by a snake in the final part of the book. It's a really fun read and it was very fitting for the character's sinuous and devilish nature.
And if comics/graphic novels count, I'd go with SV from Secretary. His struggles and, for better or worse, character growth, was done very well. Also, I had pet degus when I was younger and I thought that it was cool that this story had one as a main character.

Seems like he mainly did art for children's books. His art is very nice.
