Secret Coders 6: Monsters & Modules: 04/25/19
Monsters & Modules by Gene Luen Yang and Mike Holmes is the conclusion to the Secret Coders series. Our heroes travel to Flatland to save their school and possibly their dimension.
This book takes all the coding taught in previous volumes to do some fairly complex Logo programming which readers can do to play along.
Of course it's also fun to see the main characters rendered as 2D shapes. There is the built in misogyny of Edwin Abbott's "romance in many dimensions" that is explored when Hopper is rendered as a line and is treated as an inferior even though she by far the most competent of all them.
