Genre: Young Adult, Urban Fantasy with Elves
This book vacillated between slow and being very very good. The mystery is introduced very early in the novel, our hero, Orient, is asked to help the local cops find the dealer & manufacturer of a new drug on the market (called passport, 'cause it purportedly will allow the users into the fairy lands) that supposedly changes a human into an elf. But in actuality seems to be killing the users. It's not really a fantasy version of a police procedural, as the police in Bordertown aren't very process-oriented, and the point-of-view character is not very law/police savvy. However, the plot is basically that. The who-dunnut is eventually solved, but not very satisfactorily to my mind. We never find out WHY, and we're only briefly introduced to the perpetrators before they are revealed.
Despite my issues with the mystery, the basic idea of a drug to change humans into elves, and the social consequences of the idea (whether or not it works) is a very interesting one. Unfortunately, I find Bordertown's description and exploration much richer and more evocotive in the short stories from _The Essential Bordertown_ (ed. by Terri Windling) then I do in the longer _Finder_, which is a novel set in the same shared universe. _Finder_ does delve a bit deeper into the elfish culture then I remember any of the stories in _The Essential Bordertown_ doing, but it's still a superficial delve - it's not really important to the story, it's just providing an elfish parallel to Orient's own back-story.
The bit that most caught my attention is Orient and Tick-Tick (our hero's best friend) dissecting the behavior of another character, Linn. I'm not sure if I agree with their conclusion but it was an interesting analysis of what constitutes honorable/proper/ethical behavior. I still find myself teasing at the question days later, as I have a lot of empathy for Linn's actions.
As a warning, this is not a comedy; the end is a downer, which I'm sure has influenced my own luke-warm reaction, as I remember really enjoying the earlier parts of the novel...
