My favorite so far is American Predator by Maureen Callahan and Green River Runs red by Ann Rule, I like how Ann Rule made it more about the victims and highlighted them instead of Gary Ridgeway by M3G87 Related: Halloween Book Recs Book that focuses on threat mitigation from the point of view of decision-makers (e.g. top officials of the us gov) If you are Harry Potter/Twilight/Hunger Games fans, suggest me your next favorite book in the world. Disturbing, high concept books a la Tender is the Flesh Giving tree ideas- 4th grade mystery lover reading at 6th grade level?
