About this book
Christopher Boone, a fifteen-year-old with an extraordinary mind for mathematics and a literal way of reading the world, sets out to solve the killing of a neighbor's dog and uncovers unsettling truths about his own family. Mark Haddon writes the whole novel in Christopher's precise first-person voice, turning a detective premise into a study of perception, trust, and independence. Frequently assigned in grades 8-12, it pairs accessible prose with rich discussion material and is the basis for a Tony Award-winning stage adaptation.
