Set in a future where people can make multiple, temporary copies of themselves, Kiln People by David Brin is meant to be a sort of noir-meets-scifi novel. But I found it to be something of a slog. It just didn't seem very (and I use this word advisedly) real. Only the fact that I've enjoyed many other Brin novels got me through the first 300 pages, and by then I'd made such an investment in the dang thing, I had to push on to the end.
