Yeah, there's definitely an audiobook for 'Hyperion' out there. I listened to it last year on Audible, and it was one of those productions that actually improves on the reading experience in a way. It's not just a single narrator; it's a full cast for the different pilgrims' tales. You get distinct voices for the Consul, Sol Weintraub, the Priest's story—all of it. It really helps keep the Canterbury Tales frame narrative straight in your head when each character has a unique sound. The production quality is solid, no weird background noise or uneven volume. I found it easier to grasp some of the more dense, poetic sections when they were performed rather than me trying to parse them on the page. The Shrike's scenes are particularly effective with audio, just this chilling silence around the description of its movements. I'd say it's one of the better sci-fi audiobook adaptations I've come across.
One thing to note is that the sequel, 'The Fall of Hyperion', is also available in audio, but I think it switches to a single narrator format. That took a minute to get used to after the ensemble cast of the first book. Still good, just different. I know the whole Cantos is available across various platforms—Audible, Google Play, probably iTunes. Libraries often have it on OverDrive or Libby too, if you don't want to purchase. Well worth a listen if you're into revisiting classic sci-fi or if you find the print version a bit intimidating.
