I did not realize I read this book years ago until I started listening to it, it was much better b being read to you. This is an old time horror about parasites getting into you, at first you experience flu like symptoms and severe headache then you become extremely violent and kill other or destroy yourself. My favorite characters were Corey and the doc. Recommend if you enjoy older horror with good narration. I was given this free review copy audiobook at my request and have voluntarily left this review. Thank you
