I'm looking for books...

... with one main theme: Some ancient, powerful, hi-tech civilizations, now non-existant, with their ruins laying everywhere, and the action of book is set many, manyyyyy years after the epoch of that civilization.
Something like Xenogears (yes, yes, i know, that it is a video game, not a book, but i couldn't find any book with that theme, so i gave a game-based example.), or Origin: spirit of the past (that's an anime, but it had some "ancient" ruins).
So, please, could you give me some titles?

"The Man of the Past" by Joseph Belgenstein is one of the best books that fits your genre. A strange mixture of William Gibson and historical and fantasy novels.

Some others that are really great are "Cybertron Wars" by Daryl Nixon, "Ruins of Chternoxyl" by Conrad Ambrose, and "Prelude to a Finale" by Ryuichi Tamura.

A Canticle of Leibowitz

Thanks for so many titles, but i have searched the internet using google to find more about these books, but i cannot find anything at all about them!As if they were nonexistant, and it is surely impossible to find any of these in my nearest bookstore :(.

Thanks, found some info about that book, looks very promising :D.

Are there more books than those?

Yes, many.

try asking a LIBRARIAN!

mara and dann by doris lessing is good but quite moralistic. john wyndhams's the chyrsalids is a total classic

The Dying Earth by Jack Vance?

Lies of Locke Lamora.

Technically on theme and very enjoyable

The Stand is pretty good too though the time span is waaaaaay shorter that what you wanted

Dark tower series.

Is The Stand by Stephen King?

I loved the Tripod trilogy and the Sword of the Spirits trilogy both by Samuel Youd (under the pseudonym of John Christopher) when I was 13.  I remember it being well-written, but then again I was 13 so no guarantees.
