Now the king has summons Jian back into his service. Only a sword fighter without sight can protect the princess whose face is death to any who look upon her. Their mission is to defeat the warlock and lift the curse from the dying land. But can Jian fight well enough under her dog's guidance to survive the perilous journey? And what price will she pay for victory?
