The fourth standalone thriller in The Executive Series finds Secret Service Agent Scott Roarke on a serial assassin’s trail - one that leads to a clandestine North Korean plot and a nuclear standoff.

Instability and fear seize the nation. Local and national political figures are systematically assassinated. A growing secessionist movement stirs up anti-government fervor. The combination creates nationwide unrest and lack of confidence in leadership. With the clock ticking toward a monumental constitutional crisis, President Morgan Taylor assigns Secret Service Agent Scott Roarke to investigate the assassinations. Meanwhile, Roarke’s fiancée, an assistant to the US Supreme Court Chief Justice, is tasked with researching the separatists. Attorney Katie Kessler goes rogue to gather evidence for the court. Roarke hunts a lone assassin across two continents. Their paths lead them both to a decades-old plot hatched at a private school in Switzerland, now leading to North Korea.

With the assassin ready to make his greatest kill and critical destabilizing votes occurring state-by-state, the president must decide whether to activate America’s own secretive, long-incubating active measures against an enemy that can’t be exposed, but must be stopped. Timely and revealing, with an inside-out view of real and present dangers, Executive Force brings a political reality to life that feels like breaking news.
