The secret invention notebook belonging to eleven-year-old Julian Calendar and his friends is stolen by an evil inventor. It's up to the young scientists to save their inventions and prevent another theft. This action-packed graphic novel also touches on issues including friendship and bullying. The cartoon-filled pages are visually stimulating but make the story somewhat difficult to follow.
