The final installment of the Warhammer 40,000 megaseries, Dawn of Fire.

The first phase of the Indomitus Crusade is drawing to a close. Vast swathes of Imperium Sanctus are back under tentative Imperial control. Still the primarch Roboute Guilliman faces wars on every front. His desire to cross the Great Rift to save Imperium Nihilus remains strong, even as news of renewed assaults on Ultramar draw his attention home.

Yet it is to the galactic south that the Avenging Son must go, taking a large part of the crusade with him, for the menace of the necrons is gathering strength. Battlefleet Kallides, despatched into the dangerous null space of the Pariah Nexus some years before, is feared lost. A greater unity is being forged between the necron dynasties, and with it come whispers of a power from the ancient past returned to rule them all... Whispers of the Silent King.
