Robert Louis Balfour Stevenson was a Scottish novelist, poet, travel writer, and essayist. His most famous works are "Treasure Island" and "The Strange Case of Dr. Jekyll and Mr. Hyde." In this harrowing tale of good and evil, the mild-mannered Dr. Jekyll develops a potion that unleashes his secret, inner persona — the loathsome, twisted Mr. Hyde. This book is about losing control. It's about addiction, about giving in to your darker desires and the struggle that all people go through: wanting to do something and knowing you shouldn't.
