Query: Fantastic book~

Flowers for Algernon is beautifully written, highly emotional and a thought provoking novel. The book starts with reading Charlie's thoughts, written when his IQ is 68. He was chosen for a controversial surgery, and we get to experience his growing intelligence (IQ is 185) through his progress reports. We also get to see how people treat Charlie at all stages of his intelligence and vice versa. Algernon is the little white mouse that the experimental surgery was done on first.A remarkable timeless novel originally written in 1959.Highly recommended!
