My publisher for my second book, Bad Thoughts, came up with a cover which, being kind, wasn't very good, but they agreed to let me provide my own artwork. My friend (and my wife's cousin) Laurie Pzena is an extremely talented painter, graphic artist and photographer, and I asked her if she could come up with a cover, suggesting taking a photo at a cemetery, and what she came up with for Bad Thoughts I think is great. My publisher ended up darkening it, changing the color and font, but I always liked her version better, so when I put Bad Thoughts out as an ebook I went back to her original version for the cover.
While there are no scenes in a cemetery,
Laurie's photo expresses the grim nature of the book and that it's
horror, even though the description and first 50 or so pages might make it
seem like it's a police procedural.
