Wikipedia tells me that this is a cult classic, although I must confess that I didn’t know about it until late last year. It has an interesting structure with each chapter told through a different character, much in the tradition of The Canterbury Tales or The Decameron, gradually filling out the world setting and character backstories. Also kinda like some JRPGs. This also enabled the author to mix in a variety of different story styles, which enriched the world building and character personalities.
I found the ending quite depressing, and didn’t make me want to continue the series, but Hyperion’s strongly visual storytelling is undoubtedly ripe for screen adaptation (which seems to be happening sometime??).
