This is book two in the Secret Coders series.
Hopper, Eni, and Josh meet Professor Bee, founder of the Bee School, which has been mostly demolished and replaced by Stately Academy (the school all three friends attend). Professor Bee teaches them to code (program a robot turtle to follow specific paths). But Principal Dean and the rugby team are following them and trying to discover a secret.
The Secret Coders series follows the friends as they learn coding and try to solve the mystery of Stately Academy. Gene Luen Yang, along with being a “graphic novel superstar” taught high school computer programming.
The website (www.secret-coders.com) offers videos, activities, information, and coding lessons for interested readers.
This book is fun to read and kids could learn something too.
