Heart of Diamonds is a romantic thriller about blood diamonds in the Congo. The high-concept plot features an American televangelist, the President of the Congo, and the White House in a diamond smuggling scheme that leads to U.S. military involvement in the Congo’s civil war. When TV reporter Valerie Grey (the heroine) uncovers the conspiracy, an array of powerful forces—a ruthless mercenary, the Congolese army, and cold-blooded agents sent by the White House—try to stop her before she can expose it to the world. Heart of Diamonds also has a big romantic love triangle that feeds an important subplot.
