Longlisted for the Man Booker Prize 2018, from the author of the award-winning international bestseller Half-Blood Blues comes a dazzling new novel about a boy who rises from the ashes of slavery to become a free man of the world. George Washington Black, or "Wash," an eleven-year-old field slave on a Barbados sugar plantation, is terrified to be chosen by his master's brother as his manservant. To his surprise, the eccentric Christopher Wilde turns out to be a naturalist, explorer, inventor, and abolitionist. Soon, Wash is initiated into a world where a flying machine can carry a man across the sky, where even a boy born in chains may embrace a life of dignity and meaning—and where two people, separated by an impossible divide, can begin to see each other as human. But when a man is killed and a bounty is placed on Wash's head, Christopher and Wash must abandon everything.
