Dark Intentions [EPUB ebook] 

Everything you know about horror is true. The darkness is endless. Your fears will come to life. Your nightmares haunt you, and after you read this book, you won’t want to sleep again. But if you listen to the sound the knife makes sliding along the metal, on claws sliding down a chalkboard, the chill of death breathing on your neck, you will know it was him the whole time. Waiting for you…to die from his blade.
