"Black Lightning" is a supernatural story about a serial killer. Anne Jeffers has been writing about Richard Kraven's bloody path. And now he's due to be executed. But in his final message to her he tells her the killing won't stop with his death. And it doesn't.

I enjoyed this book. I like a good spooker.
