And then there was movement beside the bed, and something landed lightly on his legs. He felt nothing. A pair of yellow eyes looked into his own, shining like the sun. The window was open and it was cold in the room, but the warmth that came off the wolf enfolded him like a hot bath. His pup, Bran realized… or was it? He was so big now. He reached out to pet him, his hand trembling like a leaf.
When his brother Robb burst into the room, breathless from his dash up the tower steps, the direwolf was licking Bran’s face. Bran looked up calmly. “His name is Summer,” he said.
