It's Eastertide, April 1775, and in the blockaded port of Boston the conflict between the British Regulars and the Sons of Liberty rapidly escalates toward a fateful confrontation. Caught in the deepening rift that divides Whig and Tory, Elizabeth Howard is torn between her love for her prominent parents, who have strong ties to the British establishment, and her secret adherence to the cause of liberty. By night she plays a dangerous game as the infamous courier Oriole, hunted by the British for smuggling intelligence and munitions to the patriot leaders. And by day she treads increasingly perilous ground as she flirts ever more boldly with British officers close to her parents to gain access to information the rebels so desperately need.
