Firefly Wedding

To all appearances Satoko wants for nothing: beautiful, born to a noble house, and of prime marriageable age. In truth she is gravely ill and has little time left. Before she can arrange the match that would restore her standing in her family's eyes, she becomes the quarry of a mysterious assassin named Shinpei, and her plans begin to unravel. To save herself she makes one desperate offer — marriage. Where love is concerned, though, Shinpei takes “till death do us part” quite literally.
