SECRET CODERS HC 03 SECRETS & SEQUENCES (Secret Coders, 3) - Hardcover

The coders are back in the third volume of the exciting new computer-programming series by New York Times-bestselling author Gene Luen Yang. 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.
