While I'm certainly a fan of this graphic novel nonfiction series and recommend the series itself to science teachers, this one wasn't my favorite. The topic is one sure to fascinate many readers--cars and engines and some history of transportation along the way. But the organization of the book was distracting to me since it bounced from one point to another as well as moving backward and forward in time with detours into car bodies and faces and other automobile features along the way. I also found it hard to get over the fact that several of the characters had one huge eyeball that practically popped off their faces and stuck way out. I'm not sure what the point of that was. Perhaps it was intended to show that they had an eye on the future, but it distracted and annoyed me. Along with that and several pages such as the "Keep on Truckin'" double-page spread that contained too much detail and too much color, it was hard for my eyes to enjoy this particular ride. I know plenty of middle graders and high schoolers who will love this one, and I appreciated the author's efforts to show balance with a nod to women who were involved with early means of transportation and engines, but it was just too garish for my tastes.
