Something terrible has finally happened. A nuclear holocaust has destroyed civilization. For one whole year, 16-year-old Ann Burden has lived alone on her family's farm, somehow sheltered from the radiation in the valley. As she hears the final radio station going off the air, she believes she is the only person left alive. But when Ann sees smoke from a faraway campfire, she knows there is at least one other survivor. Soon an incredible figure wearing a green suit and carrying an oxygen tank appears on the road. With the intruder in her valley, she makes a chilling discovery: there are worse things than being alone. Newbery Award-winning author Robert C. O'Brien won an Edgar Award for this suspense-filled science fiction tale of a young woman determined to survive on her own terms. Narrator Christina Moore places you on the scene with Ann in a strange world with an unknown future.
