From graphic novel superstar (and high school computer programming teacher) Gene Luen Yang comes Secret Coders, a wildly entertaining new series that combines logic puzzles and basic programming instruction with a page-turning mystery plot!

Gene Luen Yang is the National Ambassador for Young People's Literature. There's something lurking beneath the surface of Stately Academy—literally. In a secret underground classroom Hopper, Eni, and Josh discover that the campus was once home to the Bee School, an institute where teachers, students, and robots worked together to unravel the mysteries of coding. Hopper and her friends are eager to follow in this tradition and become top-rate coders. But why are Principal Dean and the rugby team suddenly so interested in their extracurricular activities? From graphic novel superstar (and high school computer programming teacher) Gene Luen Yang comes the second volume of Secret Coders, Paths & Portals, a wildly entertaining new series that combines logic puzzles and basic programming instruction with a page-turning mystery plot!

Stately Academy is no ordinary school: it was once home to an elite institute where teachers, students, and robots worked together to unravel the mysteries of coding. Hopper, Eni, and Josh won't rest until they've learned the whole story, but they aren't the only ones interested in the school's past. Principal Dean is hot on their trail, demanding that the coders turn over their most powerful robot. Dean may be a creep, but he's nothing compared to the guy who's really in charge: a green-skinned coding genius named Professor One-Zero.

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? From graphic novel superstar (and former computer-programming teacher) Gene Luen Yang, comes Robots & Repeats, the fourth volume of Secret Coders. This wildly entertaining series combines logic puzzles and basic coding instruction with a page-turning mystery plot!

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.

The final volume in a series that combines logic puzzles and basic coding instruction with a mystery plot! 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!
