Hyperion II. Enjoyed it much much less than the original, I won’t be looking to the next books for at least a year, if ever.
While there are some real strengths to it, I felt the story could and should have been told in half the page count. I also just liked the first book much more for its combination of short story style.
(Read a review online saying that the first book was basically unreadable as it was basically the Canterbury tales, which is illegible, even to English students. So, each their own, ymmv, etc).
