Born in a small town in Puerto Rico, Veronica "Ronnie" Williams felt she could reach places no woman had reached in history. Her father, United States Navy Lieutenant James Williams and his Puerto Rican-born wife, Maria Ramirez, notice that their little girl is exceptionally intelligent, decisive, and quick-thinking. Soon, Ronnie's actions confirm her parents' early observations. Eventually, she graduates with honors from West Point. One of her superior officers, General Mark Hemmond, sees possibilities for Ronnie before she does, believing she will reach heights beyond anyone's imagination. It isn't until General Hemmond asks Ronnie to serve as a liaison between the military and the politicians that she starts on the fast track to the White House. Ronnie goes from the Special Forces to the Pentagon, impressing everyone in her path. But even though she's scaled the military ladder, there are more obstacles to come. The very fact that she's a woman-and a Puerto Rican woman-may end up costing her the presidency. Novelist Christopher Dupre's Sine Dubio-Without a Doubt is an entertaining political thriller that showcases one woman's fight to overcome all obstacles to become president of The United States.
