The Dangers of Fairy Compacts

I'm always eager to read a story in which a fairy comes to the human world, and this one is my favorite I've read so far. The fairy world was strange, dreamlike, and not easy to understand at first, and I admire the way those aspects of the story were written, because for me part of the appeal of this kind of work is that it's about a creature that really is inhuman. The fairy and his world weren't monstrous in any way; they were lovely, just very strange. The human character, a sweet young witch, was also wonderfully written. The sex in this story was incredibly hot, and the plot was excellent, with a certain amount of angst. I'm looking forward to reading more from this author.
