Is this constrained to Fantasy? I have a lot of Science Fiction recommendations too, but here's a small list: Riftwar Cycle (several series) by Raymond E. Feist. - high magic, great overarching themes, enjoyable all around. Most of the characters are exceedingly interesting and many are extremely high powered. Merchant Princes series by Charles Stross - More of the multiworld thing, but a great twist, also what would you do if you could introduce technology into a medieval world. Deverry Cycle by Katherine Kerr - Rebirth cycles, immortal main character watches and guides several characters through multiple lifetimes. Dark Tower series by Stephen King - Great story, ties into almost all of SK's books at some point. Earthsea by Ursula le Guin - A classic story, epic for sure. Scavenger Trilogy by K.J Parker - Dark and mysterious. Main character might be good, might be bad, but doesn't remember anything. - - A couple good series I ran across on Kindle Unlimited are: Wayward Pines Series by Blake Crouch. - Like a post-apocolyptic Twin peaks, at least at first. A bit dark, the story bothered me near the end, but still worth the read. Belial Series by R.D Brady - didn't know what to make of this one at first, "alternate history" (aliens and pyramids type), but it turns out pretty good. involves "Angels" though maybe not in the conventional sense. Magic 2.0 by Scott Meyer - two books, both very good, highly recommend. Travelers Gate series by Will Wight (surprisingly good) Silo Saga by Hugh Howey - currently reading, but great writing, IMO. There are even more Science Fiction books/series I'd highly recommend, but if you aren't into it, I won't bother you with em.
