The Khorsari Reach has been lost to the Imperium for over a decade, locked behind the warp storms that cling to the edges of the Great Rift. Its worlds have been claimed by the Death Guard, its people slaughtered by the servants of the Plague God. But these are the worlds of Ultramar, and they are protected.

Ferren Areios, Captain of the Ultramarines Sixth Company, has been dispatched to retake the worlds of the Reach and cleanse them of the Death Guard’s corruption. As the Plague Marines dig in and the death toll rises to catastrophic heights, Ferren is pushed to the limits of his Chapter’s creed.
 
Isolated in the Plague God’s domain, the reclamation fleet fights not only for the worlds of the Reach, but for what remains of Ferren’s own humanity.
