One of those books, titled The Moon Tonight Feels My Revenge, was just published by Keyhole Press. It's what Keyhole calls a "minibook"—it's just over 50 pages, and it's a collection of stories about one-man black metal bands. Yes. Here's a blurb from the back of the book:
"My only problem with this book is that it was printed with ink instead of being scrawled in goat's blood. It was a pussy move if you ask me. Other than that, I deem the Moon Tonight Feels My Revenge completely Taint-worthy. Read it by torchlight or I will fucking crush you." —Lance, The King of Black Metal
The best part is that you can buy the book with a post on Twitter or Facebook. They'll let you change the text of the post, but the link to Keyhole Press has to stay. It's a great way to get a whole bunch of new eyes on a book, and the fact that they let you choose the message you send to your friends/followers is a distinctly humane touch.
