With more than five million copies sold, Flowers for Algernon is the beloved, classic story of a mentally disabled man whose experimental quest for intelligence mirrors that of Algernon, an extraordinary lab mouse. In poignant diary entries, Charlie tells how a brain operation increases his IQ and changes his life. As the experimental procedure takes effect, Charlie's intelligence expands until it surpasses that of the doctors who engineered his metamorphosis. The experiment seems to be a scientific breakthrough of paramount importance-until Algernon begins his sudden, unexpected deterioration. Will the same happen to Charlie?

An American classic that inspired the award-winning movie Charly, Flowers for Algernon now returns to Harcourt as a Harvest paperback.
