Chia was leaning back to look at the strangest building she'd ever seen. It was shaped like the old-fashioned idea of a robot, a simplified human figure, its legs and upraised arms made of transparent plastic over a framework of metal. Its torso appeared to be of brick, in red, yellow and blue, arranged in simple patterns. Escalators, stairways, and looping slides twisted through the hollow limbs, and puffs of white smoke emerged at regular intervals from the rectangular mouth of the thing's enormous face. Beyond it the sky all gray and pressing down.
