Former Justice Department operative Cotton Malone has hunted priceless treasures and confronted ruthless adversaries around the world. Now, a grave threat to the very foundation of our country has summoned him home to America.When a bold assassination attempt is made against U.S. president Danny Daniels in the heart of Manhattan, Malone risks his life to foil the killing—only to find himself at dangerous odds with the Commonwealth, a secret society of pirates first assembled during the American Revolution. In their most perilous exploit yet, Malone and Cassiopeia Vitt race across the nation and take to the high seas. Along the way they break a secret cipher originally possessed by Thomas Jefferson, unravel a mystery concocted by Andrew Jackson, and unearth a centuries-old document forged by the Founding Fathers themselves—one squarely rooted within the United States Constitution and powerful enough to make the Commonwealth unstoppable.
