The Jessica Coran/Instinct series spans 17 books published between 1992 and 2020. The protagonist, Dr. Jessica Coran, is an FBI forensic pathologist who specializes in tracking serial killers through physical evidence and autopsy findings. Killer Instinct (1992) launched the series and established the forensic investigation framework that carries through every subsequent entry.
The series has a consistent naming pattern, with most titles ending in “Instinct”: Primal Instinct, Fatal Instinct, Extreme Instinct, Blind Instinct, and so on. The middle entries from the 2000s, including Unnatural Instinct, Grave Instinct, and Absolute Instinct, maintained the pace, while later books like Dead on Instinct (2018) and True Instinct (2020) brought the series into its third decade. Rules of Fog (2012) and The Fear Collectors (2014) are the exceptions to the Instinct naming convention.
