The Underland Chronicles #4: Gregor and the Marks of Secret by Suzanne Collins

Description

Follow Gregor in the next highly anticipated adventure in Suzanne Collins' masterful Underland Chronicles!

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 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.
