Loomis wrote this book after his 20-year theory with Michael failed. The majority of the contents of this book detailed Michael's escape from Smith's Grove Sanitarium and his attack on Haddonfield, Illinois. It also revealed to the world that his target that night, Laurie Strode, was in fact his baby sister.
Many people who read his book have shown digust at Loomis, such as Lee Brackett, Kyle Van Der Klok, and even his own assissant Nancy McDonald. One person who seemed to enjoy the book was a crazed fan named Chett Johns.
