The Giver by Lois Lowry

The book is set in a seemingly perfect community without war, pain, suffering, differences or choice, where everything is under control. The protagonist is chosen to learn from an elderly man about the true pain and pleasure of the "real" world. He discovers the dark secrets behind his fragile community and struggles to handle the burden of the knowledge of pain and the concept of individuality. He must decide whether to accept the status quo or break free, risking everything.

The 611th greatest book of all time
