Still settling into command of the ageing K’t’inga-Class Battlecruiser IKS Bardur, Captain L’rena and her crew are drawn into the growing chaos of crossed realities after a rogue Vor’Cha-Class battlecruiser attacks without warning.

The enemy is no ordinary Klingon Vessel. Commanded by Captain Vra’tok, Son of Khelar, a ruthless warrior from a fractured reality where the Empire has collapsed into civil war, the ship strikes from the wounds between universes and vanishes before honour can be answered.

As the Bardur hunts its attacker, the crew discovers that Vra’tok’s passage through reality has drawn something far worse in its wake: The Loom, hungry things that move through broken space and prey upon anything out of place.

For L’rena, the mission becomes more than revenge. To stop Vra’tok, protect the Bardur, and survive the fractures tearing at the stars, her crew must prove that even an old Klingon warship can still stand against ghosts from elsewhere.
