Books

Absolutely incredible, I’m disappointed knowing I’ll be done with it soon.

Hyperion was def one of those series that I was sad to finish, like, it impacted me that "how tf can there be no more of it" way more than the norm.

Simmons in general has a very wide variety of topics in genres & Hyperion alternates them nicely (while never really leaving sci-fi).

any suggestions

Maybe as a short palette cleanser 'The Terror' by the same author? It's completely different, but nicely done. I've read a few more books by Simmons after Hyperion & this one stood out* a bit more (it's not as polished as Hyperions, but much more than the rest I've read - overall easy to read, I like it when the setting/spaces are always explained, and most importantly it's one of those stories that I gladly let live in my mind).
Warning: it has one instance of horse riding! But it's in horny a flashback :). It's a historical fantasy with good semifictional characters, really tasteful blend of actual Inuit stories, historical nautical facts, & authors own derived reality of both, also one of the top tier "monsters" ever ... and the Hyperion-style technical description that make sense of the basically literal alien world (the same story could have been set in planet exploration).
[*Edit: I completely forgot about Ilium & Olympos. Those are sort of more of the sci-fi with the expected classical twist, but I stand by my Terror recommendation too, it just lacks interplanetary travel.]

The real suggestion (and I can't/am unable to explain why the association in my mind) is the Rama series by Arthur C. Clarke. It's prob one of the top easiest writer/books for me to read (the way things are explained & which things are explained, how characters act, etc). It's nicely logical & absurdity fantastical without it ever being fantastical for the sake of being fantastical (ie the big amazing things always make sense & don't seem forced or unlikely).
