I picked up this book because it was mentioned as one of the possible theories for what was happening in the TV show Lost. It took me a while to get through it because it is a slow, quite book. Once I finally decided to sit and finish it, I read it in one sitting. I won't say too much so that I don't reveal the conceit, but the book is quite good and worth a read on a lazy or indoor-weather Sunday afternoon. While it won't help with Lost or raise any hairs on you head, it will help you consider memory, loss, and the impermanance of human lives.
