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 the Publisher
Praise for the Secret Coders series:"Gene Yang brings computer coding to life." —Entertainment Weekly
"By the end of Secret Coders, readers will learn the three major ways that code is organized, right alongside Hopper and Eni, not as something dry or rote, but something transformative." -Wired.com
"Gene Luen Yang’s talent is prodigious, his enthusiasm contagious....Even this confirmed technophobe was ready to learn coding." —Katherine Applegate, author of Crenshaw and The One and Only Ivan

The plot thickens in this fourth installment of the graphic novel “Secret Coders” series. The story starts in the middle of the action where the previous book left off, with twelve-year-old Hopper and her friends facing a challenge. They must go through the correct doors, or encounter terrible traps if they choose the wrong one. The solution, of course, involves using coding-related principles. Eventually, Hopper, Eni, and Josh find a powerful Turtle of Light, which will help them with their next adventures. Quirky characters continue to appear, such as Professor Bee, who is not quite from this dimension. The kids must also work together to outwit a robotic cat and their nemesis, Principal One-Zero. Meanwhile, sinister plans are underway as the whole school is forced to brew up the dangerous Green Pop. The Principal also enacts a devious plan to separate the coders, forcing them to work together in secret. Some clever coding using a stolen map brings the kids closer to the truth and to possibly helping Hopper’s father. In the end, the trio is cornered by an army of evil robot ducks, leaving them on another cliffhanger. There are codes throughout the book for the reader to solve, with possible solutions also provided. As with the rest of the series, this book is an engaging way to interest students in coding. The atmosphere of mystery continues to make the story exciting on its own, and will get readers eager for the next book. Reviewer: Lisa Czirr; Ages 8 to 12.

The coding heroes are in a vulnerable position after Secrets & Sequences (2017).After an entertaining Ifelse puzzle, the multicultural team of Eni (a black boy), Hopper (a biracial Asian/white girl), and Josh (a pale boy) discover the Turtle of Light, a much more powerful (and much less literal) version than the cute turtle robots from earlier books. The other-dimensional Professor Bee, now noseless, teaches them how to use the Turtle of Light to create and dismiss constructs of "virtually immovable and unbreakable" solidified light, and they're promptly tested when attacked by Cuddles, the cat robot. After the danger has passed, Bee shows them how they can use repeats more efficiently and nest code. But this tech victory is juxtaposed with social and family conflicts: Eni's parents want him to stay away from Hopper, Hopper's mother wants to pull Hopper out of Stately Academy, and Josh is becoming girl-crazy. Meanwhile, the villainous, white Dr. One-Zero abruptly institutes a new chemistry class that will make more of his weaponized green pop. Yang's integration of coding concepts into an actual mystery plot even as he continues to deepen character development in under 100 graphic pages looks effortless; Holmes' panels continue to visualize those concepts inventively. Cool coding and forward plot motion keep this series humming. (Graphic science fiction. 8-14)
