Set in 2047 on the eve of the Binary Millennium. In the early years of the Information Age, the number has almost mystical significance: in binary notation, 2047 is 11111111111, while 2048 is 100000000000. The next change will not be for another two thousand years. Here is a world of highly advanced, cybernetically enhanced personalities, complex city arcologies and reports from the robot exploration of a long dead world - and a murder mystery as well.
