L.E. Modesitt J.R.
The amazon.com product description:
After ten thousand years in exile, the cyber-warriors return in their fleet of spaceships to the planet that rejected them: Earth.L.E. Modesitt's science fiction always seems to examine a particular issue as the author tells the story. In Archform: Beauty, the he looks at advertising and ethics, for example.
Adiamante seems to focus on themes of power and environmental responsibility, as well as personal responsibility. I'm trying to figure out if these books are all set in the same world/universe or not. Certainly he uses the same names in a lot of the books, ie "Deseret" for one of the cities.
The ending of the story is very ambiguous as well. Will the whole cycle repeat itself in a few more centuries? With Kemra at the end, there seems to be a hope for change, but will she be listened to or simply disregarded as having been 'contaminated' by the Demis of Old Earth?
There are passages in this story, such as the three legends which I found to be very thought-provoking as I read them, if only to decipher what the author was trying to say.
As noted above, personal responsibility is a running theme through a lot of his books, including Gravity Dreams.
While this is a great story, and is quite relevant to today, with the environmental issues, it's a world I don't think I'd care to live in. The responsibility side is a bit much, I think. I like my CDs and books etc a bit too much. Certainly though Adiamante is a very thought-provoking read.
Updated with the cover image and amazon.com product description in 2013. The review itself is unchanged.
