From graphic novel superstar (and former computer programming teacher) Gene Luen Yang, Secret Coders: Potions & Parameters is the fifth volume in a wildly entertaining series that combines logic puzzles and basic coding instruction with a page-turning mystery plot!

Professor 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.
