She has Gus—the guardian she was captured with. And she has a strange “guide” left behind by the one prisoner who managed to escape Raiden. The wind is also rising to her side, rallying against their common enemy. When the forces align, Audra makes her play—but Raiden is ready. Freedom has never held such an impossible price, and both groups know the sacrifices will be great. But Vane and Audra started this fight together. They’ll end it the same way.
