This is the last book in the series of the Secret Coders. The graphic novel collaborated on by two author-illustrators Gene Luen Yang and Mike Holmes.  You need some “basic” understanding of coding to enjoy the story.

Josh, Hopper, and Eni are the coders who need to create a program that will take them to a different dimension so they can save the world. They need to get into Flatland a two-dimensional plane where they must overtake the evil polygons. They need to bring back a turtle of light to fight off Dr. One-Zero. This is the sixth book of the series.
