Secret coders

To save humanity, the Coders 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.

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.

Stately Academy is just crawling with mysteries to be solved! In the last volume, Hopper and Eni discovered a robot in the supply closet and programmed him to do mischief. Now they're trapped in an underground lair, and they must use their new programming skills to escape. Hot on the heels of the highly anticipated first volume, Paths & Portals offers more of the same high-stakes adventure and real-world coding instruction. The Secret Coders series is an exciting new direction for Gene Luen Yang, one of the most popular creators in children's comics.

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?.

Determined to learn the entire history of once-elite Stately Academy, Hopper, Eni and Josh are challenged to outmaneuver creepy Principal Dean, who demands that the team turn over their most powerful robot and an even more threatening coding genius, Professor One-Zero.
