A brief synopsis; (Via Goodreads)
In American Psycho, Bret Easton Ellis imaginatively explores the incomprehensible depths of madness and captures the insanity of violence in our time or any other. Patrick Bateman moves among the young and trendy in 1980s Manhattan. Young, handsome, and well educated, Bateman earns his fortune on Wall Street by day while spending his nights in ways we cannot begin to fathom. Expressing his true self through torture and murder, Bateman prefigures an apocalyptic horror that no society could bear to confront.
Now, this book was recommended to me by my three soul mates, whom I would gladly read whatever the hell they recommended for me. I was so glad that this was one of them.
Warning: This review (and book) is not for the faint hearted. Proceed with caution.
