Two stories in one, by Daemon Manx and James G. Carlson. This is carnage mixed with meta fiction, dark and unsettling and so well-written that I wanted to call up Daemon Manx (the actual, real-life one) when I was finished and ask him: Man, are you OK?
In other words, no matter what kind of horror you like, this book will scratch that itch. Red Falls will make you squirm and gag, Deacon will make you question your reality. So, basically: a win-win situation.
