NATIONAL BESTSELLER - A modern classic--both poignant and funny--about a boy with autism who sets out to solve the murder of a neighbor's dog and discovers unexpected truths about himself and the world.

"Disorienting and reorienting the reader to devastating effect.... Suspenseful and harrowing." --The New York Times Book Review

Christopher John Francis Boone knows all the countries of the world and their capitals and every prime number up to 7,057. He relates well to animals but has no understanding of human emotions. He cannot stand to be touched. And he detests the color yellow.

This improbable story of Christopher's quest to investigate the suspicious death of a neighborhood dog makes for one of the most captivating, unusual, and widely heralded novels in recent years.
