The Giver by Lois Lowry. It is the future. There is no war, no hunger, no pain. No one in The Community wants for anything. Everyone is provided for. Jonas had never thought there was anything wrong with his Community, until he is selected as the Receiver of Memory and discovers that The Community is not as perfect as it seems. Although they appear to have everything, they are missing something of great importance.
The Giver. Appropriate for 5th grade gifted students and up. An amazing view of a dystopic community.
