I've been looking for a book I read when I was much younger, and I can't remember the name of it.
It was about this guy in New York, I think he was a private detective, and he was hired by an elf or maybe some mind of fairy, to find a unicorn or something. And I know he met up with a cat-girl. Beyond that, I don't remember much, but if anyone knows who wrote it or what it is called, I'd really like to know.
