Sharper Than a Serpent’s Tooth (#6)

Previous: Paths Not Taken | Next: Hell to Pay

My name is John Taylor. I’m a PI for hire in the Nightside, the dark and corrupt city within the city of London. Where the sun never shines and where pleasure and horror are always on sale—for the right price.

Not a nice place to visit or a nice place to live. So you wouldn’t think I would care that it was about to be destroyed, by none other than my very own long-missing, not-quite-human mom. 

But I do. I was born here, I live here, and I got friends here. They might not all be acceptable in polite company, but they’re my friends, nonetheless.

I know that I’m the only one who can stop her. The trick is, how to do it without fulfilling this prophecy that says whatever action I take, not only is the Nightside doomed, but the rest of the world will soon follow…


“Colorful and quirky characters […] packed with action and dark humor. Taylor is an eminently sympathetic hero.”
