Let's talk about books that scare you. No, not the latest Sarah Palin volume; we're talking about books that you shouldn't read at night, books that cause a genuine sense of nervous dread. Our friend Jason Vanhee wrote such a book recently, and it's available for the Kindle for a limited time. Why limited? A publisher just optioned it for print, and that means the Kindle version will soon go the way of the dodo (at least for the foreseeable future). Natalie and I have both read it and enjoyed it, so go pick it up while you still can.
