RIP, truly one of the greats.

His early stuff contains some real masterworks. Hyperion is still to this day, going to show up at the top of my scifi recommended reading list, most of his horror novels were also great in their own ways.

PS: I thought Fall of Hyperion should have been the end, it was just too final. There was plenty of space for some prequels but while the sequels contained some interesting ideas, they just never got to the level I felt justified reversing the finality of Fall. And Olympus/etc was pretty forgettable, but I don't regret the time I spent reading pretty much everything he wrote, sometimes more than once. So again, RIP.
