The Rise of Endymion by Dan Simmons

This book concludes the Hyperion Cantos and the adventures of Raul Endymion and Aenea. I found the story really moving in places and challenging in others. There are parts that were just confusing for me: I'm still not sure I completely understand the motivations of the Techno Core, for example. But I found the story both intriguing and exciting. I think I would like to re-read all four of these books, but preferably one right after the other.
