Former Secret Service agents turned private investigators Sean King and Michelle Maxwell have seen their lives splinter around them. Michelle lies unconscious in a hospital bed after a night of suicidal violence. And Sean is forced to take on a thankless investigation into the murder of a scientist just inside the CIA's razor-wire fence near Williamsburg, Virginia.

Soon he is uncovering layers of disinformation that shields a stunning world filled with elite mathematicians, physicists, war heroes, spies, and deadly field agents. Amid murder, a seemingly autistic girl's extraordinary genius, and a powerful breakthrough in the realm of classified codes, Sean learns enough to put his life at risk. Now, he needs Michelle-at her best-to help stop a conspiracy of traitors operating in the shadow of the White House itself.

From Michelle's courageous struggle to defeat her long-buried personal demons to a centuries-old secret that surfaces in the heat of the action, SIMPLE GENIUS pulses with stunning, high-intensity suspense. The heroes of Split Second and Hour Game are back-as you've never seen them before.
