“I don’t want to die,” Bitterblue said, and a tear seeped from her eye and froze on her eyelash. Katsa knelt and held the cold little bundle of girl close.

“You won’t die,” Katsa said. “I won’t let you die.” But it would take more than her own will to keep Bitterblue alive, and so she reached into her cloak and pulled out the water flask. “Drink this,” she said, “all of it.”

“It’s cold,” Bitterblue said.

“It will help to keep you alive. Quickly, before it freezes.”

The child drank, and Katsa made a split-second decision. She threw the bow onto the ground. She pulled the bags and the quiver over her head and dropped them beside the bow. Then she took off the wolf furs she wore over her shoulders, the furs she’d allowed herself to keep and wear only after the child was covered in several layers of fur from head to toe. The wind found the rips in Katsa’s bloodstained coat, and the cold knifed at her stomach, at the remaining wounds in her breast and her shoulder; but soon she would be running, she told herself, and the movement would warm her. The furs that covered her neck and head would be enough. She wrapped the great wolf hides around the child, like a blanket.

“You’ve lost your mind,” Bitterblue said, and Katsa almost smiled, because if the girl could form insulting opinions, then at least she was somewhat lucid.

“I’m about to engage in some very serious exercise,” Katsa said. “I wouldn’t want to overheat. Now, give me that flask, child.” Katsa bent down and filled the flask with snow. Then she fastened it closed, and buried it inside Bitterblue’s coats. “You’ll have to carry it,” she said, “if it’s not to freeze.”

The wind came from all directions, but Katsa thought it blew most fiercely from the west and into their faces. So she would carry the child on her back. She hung everything else across her front and pulled the straps of the girl’s halter over her shoulders. She stood under the weight of the child, and straightened. She took a few cautious steps in the snowshoes. “Ball up your fists,” she said to the girl, “and put them in my armpits. Put your face against the fur around my neck. Pay attention to your feet. If you start to think you can’t feel them, tell me. Do you understand, Bitterblue?”

“I understand,” the girl said.

“All right then,” Katsa said. “We’re off.”

She ran.

SHE ADJUSTED quickly to the snowshoes and to the precariously balanced loads on her back and her front. The girl weighed practically nothing, and the snowshoes worked well enough once she mastered the knack of running with legs slightly splayed. She couldn’t believe the coldness of this passageway over the mountains. She couldn’t believe wind could blow so hard and so insistently, without ever easing. Every breath of this air was a blade gouging into her lungs. Her arms, her legs, her torso, especially her hands—every part of her that was not covered with fur burned with cold, as if she had thrown herself into a fire.
