What this book is about
Travis Cornell, adrift after personal losses, discovers an extraordinarily intelligent golden retriever in the California hills—the product of a secret government experiment. But the dog escaped alongside something else: the Outsider, a terrifying creature engineered by the same program. Koontz's most beloved novel is a thriller, a love story, and a meditation on what makes us human, anchored by one of fiction's most winning animal characters.
