Gregor is drawn ever deeper into a brewing crisis. For generations, rats have run the mice--or nibblers--out of whatever lands they've claimed, keeping them constantly on the move. But now the mice are disappearing, and the young queen Luxa, who credits them with saving her life, is determined to find out why.When Gregor joins her on a fact-finding mission, he's relieved that this time, at least, there's no prophecy on the line. But when the true fate of the mice is revealed, it is something far more sinister than Gregor or Luxa has imagined--and it points the way to the final prophecy he has yet to fulfill. Gregor's role as a warrior and his abilities as a rager are put to the test., It's only 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 fulfil 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., Mice, or "nibblers," are disappearing, and Luxa is determined to find out why. Gregor joins her on a fact-finding mission, and when the true fate of the mice is revealed, it's something far more sinister
