Gregor the Overlander

Suzanne Collins’s debut middle-grade fantasy introduces a hidden subterranean realm where humans and giant insects, bats, and rats share an uneasy existence. When twelve-year-old Gregor accidentally drops through a laundry grate in New York City, he discovers the Underland, a vast ecosystem beneath urban foundations. Drawn into a centuries-old conflict between warring rodent and bat factions, Gregor navigates unfamiliar customs, deciphers cryptic prophecies, and confronts the moral complexities of survival. Collins grounds her imaginative world-building in themes of courage, responsibility, and the fragile balance between opposing forces. The narrative balances exploration with moments of quiet reflection, examining how ordinary individuals adapt to extraordinary circumstances. As the opening installment of a five-book series, this novel establishes a richly detailed setting and introduces characters whose loyalties shift as the underground conflict escalates. Readers interested in fantasy exploration and character-driven storytelling will find a structured entry point into Collins’s early work.
