Accelerando by Charles Stross. Recursion by Tony Ballantyne. Down and Out in the Magic Kingdom by Cory Doctorow.
Yes, these are all evolutions of previous ideas, but Science Fiction has always built on itself.
Recursion by Tony Ballantyne is a book that I didn't actually like all that much, but reread anyways. It covers a lot of topics I love (global AIs, Von Neumann Machines, tulpas, trusting trust, and a totalitarian utopia). The plot leaves a lot to be desired, but the concepts are worth it.
