In the near future, after the collapse of society as we know it, one English town survives under the protection of the computer algorithms of the Process, which governs every aspect of their lives. The Process gives and takes; it allocates resources, giving each person exactly what it has calculated they will need. Human life has become totally algorithm-driven, and James, the town bailiff, is charged with making sure the Process’s suggestions are implemented.

But now the Process is making soldiers. It is readying for war - the First World War. Mysteriously, the Process is slowly recreating events that took place over a hundred years ago, and is recruiting the town’s men to fight in an artificial reconstruction of the Dardanelles campaign. James, too, must go fight. And he will discover that the Process has become vastly more sophisticated and terrifying than anyone had believed possible.
