The Underland Chronicles Book Four: Gregor and the Marks of Secret (Unabridged‪)‬

Rich in suspense and brimming with adventure, the New York Times-bestselling Underland Chronicles unfold the fate of the Underland and the great warrior, Gregor. Suzanne Collins is also the author of the bestselling Hunger Games trilogy.

In the fourth volume of the critically acclaimed Underland Chronicles, 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 have imagined–and it points the way to the final prophecy he has yet to fulfill. Gregor’s role as warrior and his abilities as a rager are put to the test in this suspenseful, action-packed penultimate installment of Suzanne Collins’s thrilling Underland Chronicles.
