The first in a gripping young fantasy series from the author of THE HUNGER GAMES. When eleven-year-old Gregor falls through a grate in the laundry room of his apartment building, he hurtles into the dark Underland, where spiders, rats and giant cockroaches coexist uneasily with humans. This world is on the brink of war, and Gregor's arrival is no accident. But Gregor wants no part of it - until he realizes it's the only way to solve the mystery of his father's disappearance. Reluctantly, Gregor embarks on a dangerous adventure that will change both him and the Underland forever. Engrossing, page-turning fantasy, full of vivid battle scenes. Perfect for fans of Percy Jackson or Beetle Boy. Collins' young fantasy novels are fast-paced, sad and funny, and perfect for both boy and girl readers. Fantastically engaging. - Publisher's Weekly
