Hopper lives with his siblings in a pet store. They believe they will one day be adopted and go to their forever home. That belief is shattered when they realize they are to be sold as snake food. The mice escape, but Hopper is separated from Pinkie and Pup. He ends up below Brooklyn and is taken in by a rat named Zucker. Turns out Zucker is the prince of Atlantia, a rat haven controlled by King Titus. Hopper is taken in by the king, but finds out that he bears a striking resemblance to the prophesied chosen one who will one day liberate the mice of the underworld. The more he learns about the rats and the mice, the more he is unsure of who is right or wrong. How can one little mouse be the salvation they were looking for?

This book was actually not as bad as I thought it was going to. I am generally not a fan of animal books and the cover didn't give me any hope that this one would be better than the rest. While the book definitely doesn't break any new ground story-wise, it is entertaining. I am sure fans of Redwall and the Warriors series will enjoy this swashbuckling tale.
