I first read this story many years ago and am thrilled to see they've reprinted it since I lost my copy. The story is about professional Dreamers, people who create stories to be injected straight into a persons mind while they sleep. Most Dreamers can only create stories with a limited locale and a limited number of characters. A very few, however, can create whole worlds. When one of those master dreamers goes crazy, his audience becomes trapped in the world he created, unable to wake up, convinced they are in reality. Whether or not they can be freed asks everyone to question all beliefs they hold dear. It is an exciting, well-written story, that has made me question many of my own values and beliefs many times, since this book questions the inflexibilty of fanatacism. And now that we are post-9/11 the message I found with this book rings louder and louder.
