(3) 4-6 The graphic novel series continues without preamble. The secret coders must use coding principles to overcome former Bee School student turned misguided do-gooder, Dr. One-Zero. Challenges presented build on skills from earlier episodes; this third book, with its clean comics style, creatively packages programming lessons within a story line that engages returning readers.

(3) 4-6 The ongoing story and interactive lessons resume in this fourth entry. Hopper, Eni, and Josh continue to use coding skills--and now Professor Bee's triangular Turtle of Light--to combat the evil principal, Dr. One-Zero, whose new plan involves having students produce dangerous "Green Pop." Readers engaged with the series arc will enjoy the graphic novel's easy-to-follow visuals, solvable puzzles, and growing mystery.

(2) 4-6 Stately Academy looks more like a haunted house than a school--at least to twelve-year-old newcomer and narrator Hopper. But she finds a like-minded ally in basketball star Eni. Nosing around campus, the two find programmable robots and pages of code. This graphic novel is an inspired mash-up of computer science and mystery, thanks in part to well-thought-out explanations and, more importantly, visuals.
