The name's John Taylor. I work the garish streets of the Nightside—the hidden heart of London where it's always three A.M., where inhuman creatures and otherworldly gods walk side by side in the endless darkness of the soul. I have a talent for finding things. People...property...no problem. But now I'm after something different. A local diva called the Nightingale has cut herself off from her family and friends, and I've been hired to find out the reason. I'm also wondering why her suicide-prone fans think she has a voice to die for. Literally. To get the truth, I'll have to lend an ear to the most enticingly beautiful and deadly voice in all of the Nightside—and survive.
