Led by Yulan, their charismatic captain, the Free have spent years selling their martial and magical skills to the highest bidder -- winning countless victories that have shaken the foundations of the world. Now they finally plan to lay down their swords. Yet when Yulan is offered a final contract, he cannot refuse -- for the mission offers him the chance to erase the memories of the Free's darkest hour, which have haunted him for years. As the Free embark on their last mission, a potent mix of loyalty and vengeance is building to a storm. Freedom, it seems, carries a deadly price.
