Book excerpt: One exceptional boy journeys into the ashes of society to find the cure for a devastating plague in this riveting post-apocalyptic standalone set in the same world as the USA Today-bestselling The Girl With All the Gifts. Once upon a time, in a land blighted by terror, there was a very clever boy. The people thought the boy could save them, so they opened their gates and sent him out into the world. To where the monsters lived. "Strange and surprising and humane" (Lauren Beukes), The Boy on the Bridge is a gripping, powerful story that will make you question what it means to be human.
