This is an amazing book. Very complex, very thought provoking. This is not a light read, but it's well worth it. In it, you are the main character, referred to as the "reader", who is confronted over and over again with books that for one reason or another end just after they begin. While trying to find the remainder of these mysterious books, you, the reader, begin to unravel a metaphysical plot, and reality begins to come undone.
