If you've read any reviews on this book you've seen the word "haunting" mentioned. This is true! The story isn't very climatic, but it is interesting, and the writing is very descriptive, and thoughtful. I enjoyed many of the reflections and analogies that the main character describes throughout the book, particularly some of the passages concerning loneliness. There are many people in this world who have personalities that draw them away from others into seclusion. This book helps one take a glimpse into the world of those who have such personalities, and can help us gain a better understanding of one another in general. I really liked it! 
 A few good quotes: 
 "Because, once alone, it is impossible to believe that one could ever have been otherwise. Loneliness is an absolute discovery." 
 "Having a sister or a friend is like sitting at night in a lighted house. Those outside can watch you if they want, but you need not see them. You simply say, "Here are the perimeters of our attention. If you prowl around under the windows till the crickets go silent, we will pull the shades. If you wish us to suffer your envious curiosity, you must permit us not to notice it." Anyone with one solid human bond is that smug, and it is the smugness as much as the comfort and safety that lonely people covet and admire." 
 "It was a source of both terror and comfort to me then that I often seemed invisible -- incompletely and minimally existent, in fact. It seemed to me that I made no impact on the world, and that in exchange I was privileged to watch it unawares."
