Gregor The Overlander

The author wrote this book name is Suzanne Collins.
I'm not finish the book but i just read the half way of the book.

The summary is talking about when eleven year old Gregor follows his little sister through the grate in the laundry room of their New York apartment building, he hurtles into the dark Underlander beneath the city. The humans live uneasily beside giant spiders, bats, cockroaches, and the rats but the fragile oeace is about to fall apart.

Gregor wants no part of a conflict. He just wants to find way home. But when he discovers that a prophecy foretells a role for him in the Underland's future, he realizes it might be the only way to solve the biggest mystery of his life. Little does he know his quest will change him and the Underlander forever.

I don't remember what he reminds me of.
