An assassin with fancy fairy/elven technology is tasked with down illegal supernatural immigrants in LA to keep things stable for the elves that are already living there. I liked that this story remained a little cagey about the exact nature of its faery/elf/whatever creatures, although that may have been because I'd read Welcome to Bordertown fairly recently, and had no problem inserting the version of elves from Bull's contribution to that anthology into this story as well, although I have no idea if that's what she intended. (Probably not.) The idea of an assassin listening to one of his victims and wondering about his employers' motives has been done before, but that plot made for an interesting mix with the supernatural elements and the traces of environmentalism.
