Pandemonium

I recently came across this book on Amazon, and I wasn't sure if anyone had read or heard anything about it worth sharing. It says it is a debut novel and falls into scifi and horror genres. It is set in an America where for the past few decades demon possession has become more and more common, but the demons are something like comic book characters rather than what we normally would think of as a demon. At some point, scifi writer Philip K. Dick is possessed, and the main character has been possessed since he was a child. It sounds strange but definitely has me intrigued.
