We Who Sleep Three Ghosts in the Machine Book Three

The year is 1762 and the rough seas are threatening and treacherous--but they have nothing on Captain William Dearborn. Dearborn, captain of the Deadly Vagabond, is master of both his ship and his men--who know to turn a blind eye to his nefarious activities. But when a faulty compass guides them from their chosen course, his past comes back to haunt him. Those who sleep have awakened, and Dearborn is the only thing standing in the way of the rest they desire.
