Pandora's Star has a direct sequel: Judas Unchained, and Peter F. Hamilton has other books in that (The Commonwealth) millieu.

Additional authors you might enjoy are Neal Asher, Iain M. Banks, Alistair Reynolds, and Jack McDevitt.

Yeah, I've read the commonwealth.

But nothing like the first book, although the two are actually a single book sold separately, at least for me.

I just read a neighbor of Pandora's Star in the graph (Coyote) and enjoyed it. Note quite like pandora, but fine.

Allen Steele's work isn't really all that similar, though I suppose Coyote and its sequels come closest. The authors I mentioned are much better bets.
