Potions & Parameters
by Gene Luen Yang (Author) Mike Holmes (Illustrator)
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.
