This rat/mouse world is almost as violent and rich in folklore as the rabbit world of Watership Down. The book is certainly not for cat lovers; the cats in this fantasy world are downright evil. Hopper is a bit slow on the uptake and naive, and his sister, Pinkie, is so full of herself that one is tempted to shake her out of her pride and foolhardiness.
The characters and the plot twists carry this 313 page introduction to the utopian/dystopian world of Atlantia. Hopper is endearing if dim. His friend Zucker the Rat Prince is hilariously brave and faithful. The Emperor Titus, Zucker’s father, is enigmatic in a Star Wars Darth Vader way. It took a while for this reader to figure out whether Titus was a good guy, misunderstood, or a really bad guy. (My only excuse is that it takes Hopper a lot longer to figure things out.) Zucker’s friend, Firren, is undeveloped as yet, but promising. And Pinkie is annoying.
I should also mention the illustrations by Vivienne To. They’re brilliant. I’m no art critic, but I can say that I paid attention to the illustrations far more than I usually do, and they added a great deal to my understanding and enjoyment of the story.
Mouseheart is obviously the beginning of a series. The ending reveals that: “A war had begun. Somehow Zucker and his new friends were going to have to win it. Deep in his heart, he knew that they would.” If you want to learn more about the world or about the follow-up books in the series, you can try the Mouseheart website. The second book, Hopper’s Destiny, is promised for March 2015, and the third book is as yet unnamed and without a projected publication date.
