Whoops, i suggested it, but havn't been keeping up to date.

This is a wonderful and highly original novel about a mentally challenged man named Charlie who wants to be smart. One day, his wish was granted. A group of scientists select him for an experimental operation which would to raise his intelligence to genius level (Algernon being the genius mouse that it was first tested on). Suddenly, Charlie finds himself transformed, and life, as he knows it, changes dramatically.
I found that best part of this book is not so much the plot thought, but the brilliant characterisation of Charlie. His growing inteligence allows him to evaluate and comment on how life has treated him, and as much of the book is in the form of the progress reports Charlie writes about himself it is intensely personal.
I would definately recomend reading this to everyone, especially those with a low opinion of SF - and giving it as an Xmas present to any bullies you know
It also won the Hugo for best novella, and Nebula for best novel.
we read it in elementary school
I'm not sure what elementary school is, but if it's like British primary school then you are very lucky. At my schools we never read any novel that wasn't written especially for children (bloody Moonfleet!), even in top set at high school. Plus, according to the link below, its one of the most challenged books of the '90s in american libraries.
