what is the main conflict in gregor the overlander
Gregor the Overlander Eleven-year-old Gregor is left home alone in his family's New York City apartment to watch his sisters and grandmother. When Gregor's baby sister Boots falls through an old air duct grate in the building's basement, he dives in after her. The two fall miles below into the Underland: a subterranean world home to humans with near-translucent skin; giant sentient bats, rodents, and insects; and an escalating conflict between the human city of Regalia and the rats' King Gorger. They meet several "Underlanders", among them the Regalians' crown princess Luxa, her cousin Henry, and the bats who are "bonded" to them. At first, Gregor wants only to return home, but when he is attacked by two rats during an escape attempt and saved by the Underlanders, he inadvertently brings the conflict between the two groups to a head.
