The year is 1610. Continental Europe is briefly at peace after years of war, but Henri IV of France is planning to invade the German principalities. In England, only five years earlier, conspirators nearly succeeded in blowing up King James I and his Parliament. The seeds of the English Civil War and the Thirty Years War are visibly being sown, and the possibility for both enlightenment and disaster abounds. But Valentin Rochefort, duelist and spy for France's powerful financial minister, could not care less. Until he is drawn into the glittering palaces, bawdy back streets, and stunning theatrics of Renaissance France and Shakespearean London in a deadly plot both to kill King James I and to save him. For this swordsman without a conscience is about to find himself caught between loyalty, love, and blackmail, between kings, queens, politicians, and Rosicrucians, and the woman he has, unknowingly, crossed land and sea to meet.
