Hrm...off the top of my head:
- Peter F. Hamilton's "Night's Dawn" trilogy.
It starts with a complex science fiction world - genetic engineering, trading, competing philosophies...then the Dead Rise. Not zombies - vengeful, damned souls that possess the living and imbue them with supernatural powers.
I wished my eyes could move faster, reading everything but "The Naked God." (I read pretty fast - just wanted more, more, more.)
- Stephen Donaldson's "Chronicles of Thomas Covenant."
I can't even begin to describe these. All I can say is, when I went to see LOTR, I was painfully disappointed to think that these books would never get a similar treatment. Just wouldn't work.
(They're both stories with strong Christian themes, and rings of Power. It's just that Tolkien's good guys are Heroes that are outmatched by Evil. Covenant is a normal person catapulted into a fantasy world and imbued with power beyond imagination - far beyond that of his enemy - that he doesn't know how to use. Worse, as a normal person faced with horrors from a fantasy world, he's an ass, most of the time.)
- Harry Harrison's "West of Eden."
This is the most genuinely alien world I've ever read about, but it all takes place right on Earth. Just an Earth where the dinosaurs never died out - they evolved into humanoid life, while humans developed in the colder reaches.
The series is about the two races meeting, and trying to wipe each other out. The Yilane (dinosaur types) are amazing - living biotechnology, communication by sign language (and limited color changes in the skin), strange customs...and the humans are pretty human. I reread those a bunch of times.
