Secret Coders Vol. 4: Robots & Repeats

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, Secret Coders is a wildly entertaining series that combines logic puzzles and basic coding instruction with a page-turning mystery plot! Available in Softcover and Hardcover editions.
