I n the middle of a walking forest of black hats stood a white-haired woman with bright blue eyes. The men seemed no more to see her than they saw whatever Ash was flying, which Lev said they couldn’t, though they felt the turbulence, each one reaching up to hold his hat as he walked through it. They walked around the woman as she stood there, looking up at what they couldn’t see, one gray-gloved hand holding a little hat against the downdraft.
