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.
