I bought and read John Varley's Mammoth-not bad, sort of scifi light, and then moved on to Allen Steele's Tranquility Alternative. Anyone who hasn't read Steele's non-Coyote books should give them a try. I have yet to read one I didn't like. He creates worlds we don't just enjoy but that we know-even when they are alternative history like this one. Give him a run, you will thank me.
