All men are islands, surrounded by the bottomless oceans of unthinking night.
It's the twenty-seventh century, when interstellar travel is by teleport gate and conflicts are fought by network worms that censor refugees' personalities and target historians. The civil war is over and Robin has been demobilized, but someone wants him out of the picture because of something his earlier self knew.
This week's book is Charles Stross's Glasshouse and we'll be meeting at The Fletcher Moss on William Street in Didsbury.
