Thank you so much! I decided to describe it as a picture book “written in C code” rather than “about C code” to emphasize how it’s distinguished from other educational programming books…it contains simple full C programs in which the code represents the story’s situations, so it actually is “written in C code”! 
Since this is a landing page for the book, I don’t have a hyperlink to my company website. The illustrator is a freelance artist.
