Peace is not freedom. Peace is merely the absence of war.

The First Interstellar War is over, but the Royal Navy still has plenty of work to do. As Earth struggles to recover from the bombardment, Captain John Naiser is placed in command of HMS Warspite - an experimental heavy cruiser - and ordered to escort a squadron of colony ships to a star system of immense strategic importance.

But as the crew struggle to survive hundreds of light years from Earth, they find themselves dealing with the legacy of the war ... and a threat which may sow the seeds of renewed conflict, or a deadly civil war that will rip the human sphere apart.
