Secret coders / Yang, Gene Luen

"The Coders always knew their programming skills would take them far, but they never guessed they would take them to another dimension--or to be accurate, one dimension less. To save humanity, Hopper, Eni, and Josh must travel to Flatland, a dangerous two-dimensional world ruled by polygons. If they can return home safely with a Turtle of Light, they might just stand a chance in their final showdown with Dr. One-Zero!"--Back cover.

Welcome to Stately Academy, a school which is just crawling with mysteries to be solved! The founder of the school left many clues and puzzles to challenge his enterprising students. Using their wits and their growing prowess with coding, Hopper and her friend Eni are going to solve the mystery of Stately Academy no matter what it takes!.

"Dr. One-Zero won't stop until the whole town--no, the whole world--embraces the 'true happiness' found in his poisonous potion, Green Pop. And now that he has the Turtle of Light, he's virtually unstoppable. There's one weapon that can defeat him: another Turtle of Light. Unfortunately, they can only be found in another dimension! To open a portal to this new world, Hopper, Eni, and Josh's coding skills will be put to the test"--Back cover.

"Dr. One-Zero has added a new class to Stately Academy's curriculum. But in 'advanced chemistry' they only teach one lesson: how to make Green Pop! While their classmates are manufacturing this dangerous soda, the Coders uncover a clue that may lead them to Hopper's missing dad. Is it time to use Professor Bee's most powerful weapon: the Turtle of Light?"--Back cover.
