A year has passed since the events of Ascension Point, and the galaxy shifts uncomfortably as the opposing forces of progress and tradition threaten the new and fragile peace. Titan society teeters on the brink of civil war, the Commonwealth bristles with hostility towards the returning Seryn, while the Collective remains silent in the spaces between the stars, watching. And waiting.Against this backdrop of turmoil and unrest, the Peacetrooper brother of Commonwealth Senator Neela Kane has gone missing. Intelligence places him on Karak, an Independent desert world, and Operative Dante Zo is dispatched to bring him home-or confirm his demise. Quinn, employee of the shadowy Seryn Agency, is also headed to Karak, where rumours abound of a fierce and sudden tribal war centred on a mysterious woman with uncanny power: Venus, the Seryn's most dangerous rogue agent.Meanwhile, on Karak itself, other forces bring their pieces into play. Tasha, a young but mercurial assassin, is unleashed to kill the foreign witch and bring peace back to her home. But with a renegade Titan mercenary at her side, Venus will let nothing stand in the way of her plan-and the conquest of Karak is just the beginning. With a world in the firing line, and the fate of the entire galaxy at stake, only one question remains:In the name of duty, is there anything that can't be sacrificed?
