A high-octane thriller that sets Dan Clifford against ancient secret societies vying for power in the modern world; in the vein of Dan Brown's Robert Langdon series.

In The Third Instinct, author Kent Lester brings his signature blend of cutting-edge science, history, and pulse-pounding action to the latest Dan Clifford adventure. A shadowy group of bio-hackers called the Firemen threaten to worsen the Covid pandemic by releasing an even more lethal version of the pathogen. But what drives the Firemen and how do their motivations relate to the wealth of the Roman Empire and to the third basic human instinct? The answers may lie with prediction scientist Dan Clifford. Unemployed and struggling with two years of pandemic isolation, he is rebuilding both his career and personal life. His plans to propose to his adrenaline-junkie girlfriend, Rachel Sullivan, are interrupted by the FBI. Dan must connect a maze of clues from the shadowy underworld of Savannah's hacker community to the ancient powerbrokers of Rome and in doing so, uncover a hidden agenda of big Pharma and a two-thousand-year-old battle for control of public opinion.
