In a future where humanity has conquered death and disease, the only form of permanent death is gleaning—performed by robed Scythes who cull the population to prevent overgrowth—and two teenagers are chosen as apprentices to a Scythe with very different philosophies about how life and death should be managed. A richly imagined, philosophically serious YA dystopian novel exploring the ethics of choosing who lives and who dies. The first book in the Arc of a Scythe trilogy.
