Aw, thanks everyone!
I agree with Ilan: the Nina Allan story was awesome--a sheer piece of brilliance.
Is it just me, or has this been nominated for quite a few things now?
Er, not that I know of? It's been picked up by another Best, Allan Kaster's Top Ten Tales of Science Fiction 3 (audiobook/ebook version), though. I don't have a TOC, but I've seen that Peter Watts and Ian MacLeod ("The Things" and "Re-crossing the Styx", respectively) would be in there as well.
