Japan, 1500. Aderyn Aquilla wakes to the clamor of war. An hour later, she is the only European on the ship alive and is face-to-face with an evil samurai with a sword at her throat. How will she save herself? Sanematsu Yoshihide has seen more bloodshed in his short life than he ever imagined and cannot bring himself to spill more. But what will he do with the stranger who could bring civil war to his domain on the island of Kyushu? Together, Aderyn and Sanematsu defy convention and the imperial decree that all gaijin must be put to death. Can a man whose traditions and dedication to duty are as much a part of him as his blood challenge the very basis of his existence and those who would govern it and survive?
