Singer of Souls

From the front flap of the Tor first edition: "Leaving his life of petty crime and drug abuse behind, young Douglas flees from Minneapolis to Edinburgh, Scotland, to his stern but fair-minded Grandma McLaren, who will take him in if he can support himself. Fortunately, few cities are friendlier than Edinburgh to a guitarist with a talent for spontaneous rhyme, and soon Douglas is making a decent living as the busker who can write a song about you on the spot. But Edinburgh has its dangers for the unwary. The annual arts festival, biggest in Europe, draws all manner of footloose sorts, and when a mysterious but alluring young girl offers him drugs, Douglas's resolve fails him. What follows isn't what he expects. Suddenly, Douglas can see, in all their beauty and terrifying cruelty, the fey folk who invisibly share Edinburgh's ancient streets. Worse, they can see him, and they're determined to draw him into their own internecine wars - wars that are fought to the death."
