walls; cube files, film files, old-fashioned books, stacks of paper. There were a few ornaments: a graceful swirl of what looked like blue-green glass, stiff human figures in brown pottery, an amateurish but very bright painting, a lopsided lump that could only be a favorite child’s or grandchild’s first attempt at a craft. A large flatscreen monitor, control panels. Above was another of the shallow domes, this one lined with what looked like one sheet of white ceramic. The low couch she sat on was upholstered with a nubbly cloth. She was absurdly glad to be sure it was not leather. Fluffy pillows had been piled, making it comfortable for her shorter legs.

Zebara had seated himself across from her, behind a broad curving desk. He touched some control on it and the desk sank down to knee height, becoming less a barrier and more a convenience. Another touch, and the room lights brightened, their reflection from the dome a clear unshadowed radiance like daylight.

“It’s . . . lovely,” said Lunzie.

She could not think of anything else. Zebara gave her a surprisingly sweet smile, touched with sadness.
