Publisher's summary
The Great Houses hold chains that bind time and space. They are the Namers and the Makers, of all that is. Their power is incalculable. And they are at War.

But the nature of their Enemy has always been shrouded, in mystery, in enigma, perceived through mirrored labyrinths seemingly constructed as much by the Great Houses as the Enemy. Why?

Perhaps now the secrets of the Enemy can be revealed. Or perhaps not.

Experience the ravaged memories of those who have met them in War.
