Starting with Gregor the Overlander, these books center on an amazing underground world populated by GI-NORMOUS creatures such as bats, cockroaches, spiders, and rats. A secret underground colony of humans vies for power against the deadly rats.
What I love most about these books is that they tell a complete story, in a clear arc that builds in intensity and darkens with each installment. Beginning as an edge-of-your seat adventure, books 2-5 tackle the morality of preemptive murder, biological weapons, genocide, and the brutality of war.
Book 1: Gregor the Overlander
Book 2: Gregor and the Prophecy of Bane
Book 3: Gregor and the Curse of the Warmbloods
Book 4: Gregor and the Marks of Secret
