America, 2028. A young African American investment banker joins with his estranged father, and a tech-savvy half-brother he never knew he had, to track down a cell of domestic terrorists threatening to wreak havoc on the country prior to the upcoming presidential election.

Mark Morton suspects that a pair of community activists are secretly responsible for a growing number of terrorist acts targeting random citizens and high-profile political leaders in Washington, D.C. Putting aside his differences for the sake of democracy's future, he enlists the help of his estranged father, Harry Morton, a former Philadelphia city councilman who went on to a business career with secretive contacts to Washington's intelligence community. Together with his newly revealed brother Alaka'i Liu—a brilliant, Hawaiian-born, polyracial, Cal Tech-educated climate scientist—the three join together to hunt down and stop the radicals, led by an unlikely pair, one a former Black nationalist and the other a White supremacist.

Reunion in Paradise is both an international thriller and a family drama, taking readers from the deep waters of one family's complicated history to the far corners of the world.
