The fifth Culture book from the awesome imagination of Iain M. Banks, a modern master of science fiction.
Two and a half millennia ago, the artifact appeared in a remote corner of space, beside a trillion-year-old dying sun from a different universe. It was a perfect black-body sphere, and it did nothing. Then it disappeared.
Now it is back.
Praise for the Culture series:
