From the cover:
"Charlie Gordon is about to embark upon an unprecedented journey. Born with an unusual low IQ, he has been chosen as the perfect subject for an experimental surgery the researchers hope will increase his intelligence - a procedure that has already been highly successful when tested on a lab mouse named Algernon.
As the treatment takes effect, Charlie's intelligence expands until it surpasses that of the doctors who engineered his metamorphosis. The experiment appears to be a scientific breakthrough of paramount importance, until Algernon suddenly deteriorates. Will the same happen to Charlie?"

A very sad story. Not only the end, but also Charlies past: The mother and the teachers who think they could bring him to learn by violence, the collegues in the bakery, who make fun of him and professor Nemur, who does not see a person in him.
I hope and think, that today the attitude towards mentally disabled people has chenged to the better. If so, it may partly be because of this book.

Waits now for new readers
