I read The Chronicles of Amber after reading Lord of the Rings in the 80s, loved it. Read both again in the 90s and haven’t been back, considering revisiting. I’ve never read Lord of Light and This Immortal, may add that to my TBR list. Hey OP, yes for sure to all three of the ones you’re considering. The Expanse is bar none, a league of it’s own. Hyperion is classic and very original, Red Rising is a good tale, leaning to YA but very readable and hard to put down once you’re drawn in.
