"When people are cruel it's often said that they have no heart, only a cold space or lump of ice in their chest. This was never true of Avalon. She had no heart, everyone knew, but there was nothing cold about her. IN her chest burned an enormous coal, white-hot, brighter than the North Star. North knew the truth about Avalon: she was made of fire, and she would burn them all."
