This irresistible first novel tells the story of a quiet boy who embarks on a dangerous quest in order to fulfill his destiny -- and find his father -- in a strange world beneath New York City.

When Gregor falls through a grate in the laundry room of his apartment building, he hurtles into the dark Underland, where spiders, rats, cockroaches coexist uneasily with humans. This world is on the brink of war, and Gregor's arrival is no accident. A prophecy foretells that Gregor has a role to play in the Underland's uncertain future. 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.

Grade 4-8-In this accessible, almost-cinematic fantasy, Gregor and his two-year-old sister fall into an amazing underground world. Taken in by people who have lived beneath the earth for centuries, the 11-year-old learns about the giant-sized talking creatures that also reside there, including bats, cockroaches, and vicious rats. Gregor just wants to get home, but a prophecy hints that he may be the "overlander" destined to save the humans from the warlike rodents. He is reluctant until he learns that his father, who disappeared from their New York City home a few years before, is a prisoner of the rats. Gregor is not an eager hero, but with common sense, quick thinking, and determination he grows into the role. His sister, who provides some comic relief, also plays a key part because of her ability to befriend creatures, especially the giant cockroaches. Plot threads unwind smoothly, and the pace of the book is just right. Exciting scenes and cliff-hanger chapters are balanced by decisions and interactions that drive the action. Gregor is not the most compelling figure at first, but as the story progresses he becomes more interesting, maturing through the challenges he faces. Supporting characters are generally engaging, particularly the enigmatic warrior rat that claims to support the protagonist's mission. This is an engrossing adventure for fantasy fans and for those new to the genre.

Starred Review Gr. 4-7. What if Alice fell down an air vent in a New York City apartment building instead of down a rabbit hole? Collins considers a similar possibility in her exceptional debut novel, a well-written, fast-moving, action-packed fantasy. Eleven-year-old Gregor expects a long, boring summer of baby-sitting his two-year-old sister, Boots, and his senile grandmother. Distracted with thoughts about his father, who disappeared three years ago, Gregor belatedly notices that Boots has crawled into an air vent in the laundry room. He dives in after her, and the two are sucked downward into the Underland, a fantastic subterranean world of translucent-skinned, violet-eyed humans, and giant talking cockroaches, bats, spiders, and rats. Eventually, the terrified Gregor is transformed into a warrior hero who leads a successful battle against an army of invading rats and discovers his father, who has long been held prisoner by the enemy. Collins creates a fascinating, vivid, highly original world and a superb story to go along with it, and Gregor is endearing as a caring, responsible big brother who rises triumphantly to every challenge. This is sure to be a solid hit with young fantasy fans. Ed Sullivan
