The Ghost with a Knife at Her Throat: The Book of Sight

I loved the character of Asher Gale. He reminded me of hard boiled detectives like Phillip Marlowe. That can be a tricky characterization to get right and Hincker hits the nail on the head. The addition of Asher Gale's ability to see different ultraviolet colors made his investigation unique. We get some answers to the mystery, but there are still other answers out there to be had, so it makes you want to keep reading the next novel.
If you like detective fiction and propulsive narrative, you have to pick this book up.
