It's only been a few months since Gregor and Boots returned from the Underland, leaving their mother behind to heal from the plague. Though Gregor's family receives frequent updates on her condition, they all know Gregor must return to fulfill his role as the warrior who is key to the Underlanders' survival. Accompanied by his now-talkative little sister Boots, still considered the honorary "princess," Gregor joins forces with another princess - 12-year-old Luxa - and Ripred the rat to defend the Underlanders and the vulnerable "Nibblers," or mice, from the rat army.
I liked this book better than the previous one. I was starting to feel like the series was a bit slow after reading the third book, but this one zipped by and I'm anxious to read the next.
