I have always been a huge fan of fantasy/sci-fi novels as well as novels that make you think. The Hyperion series is one of the best out there, right along with Dune. But the Hyperion series goes even farther into such thought provoking questions about immortality, intelligence, what makes something "human", evolution,religion, and, most thoroughly, time. Although the entire quintet is fascinating, The Rise of Endymion greatly surpasses all previous installments with a tremendous blend of action, philosophy, and a very well-done and tasteful love story. I highly recommend this book to any and all looking for a good read but aren't afraid to use their brain a little, or a lot. I warn you though, read the first three otherwise this will be one of the most confusing experiences of your life.
