But then the hack starts in: out of nowhere, rough, racking, shooting bits of blood and God-knows-what-all onto the page before me. And funnily enough, I realize it’s the hack that’ll keep me writing, no matter what mental jitters I get. Dr. Kreizler’s told me what this cough probably means; I’m not sure how many more years or even months I’ve got left on this earth. So let Libby Hatch come after me for trying to tell her story.
