omnibus of THE STAR FRACTION (1995) + THE STONE CANAL (1996) + THE SKY ROAD (1999) - (a Hugo-nominee for "best novel" in 2001.) These did not see American publication until 2000/2001.

I've read all of Ken MacLeod's "Fall Revolution" series - and I am quite impressed. These books are not sequential, or necessarily part of one timeline. As far as I can tell, MacLeod is playing riffs on some important future events and those involved in them - and exploring different outcomes with great zeal. His idea is that there are (will be) several "key" players that history will pivot about - but that worlds or outcomes will be vastly different, dependent on seemingly minor changes in set-up (kinda like weather.) MacLeod is smart, inventive, politcal - he won't bore you. For detailed plot summaries or analysis, here are some links I found when I did a search for reviews of this book.

Ken MacLeod's TheStone Canal (1996) - nominally second in his "Fall Revolution" series.
[Set-up/summary from the back cover of a paperback]:
Life on New Mars is rough for humans, but death is only a minor inconvenience.The machines know their place, the free market rules all, and only the Abolutionists object. Then a stranger arrives on New Mars, a clone who remembers life on Earth as Jonathan Wilde, the anarchist with a nuclear capability who was accused of losing World War III. That stranger remembers David Reid, New Mar's leader... and the women they fought over and ideals they once shared. Moving from twentieth-century Scotland through a tumultuous twenty-first century and outward to humanity's settlement on a planet circling another star, TheStone Canal is idea-driven SF at its best, making real and believable a future where long lives, strange deaths, and unexpected knowledge await those who survive the wars and revolutions to come.
