The Coders always knew their programming skills would take them far, but they never guessed it would take them to another dimension! To save humanity, they must travel to the two-dimensional world of Flatland. Only there they can acquire a weapon powerful enough to defeat Dr. One-Zero, but to open the gateway to Flatland, they must write their most difficult code yet! 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!
