Book 1 in the Dark Imperium Trilogy.
Fell times have come to the galaxy. Cadia has fallen, destroyed by the
onslaught of Chaos. A Great Rift in the warp has opened and from its
depths spew daemons and the horrors of Old Night.
But all hope is not lost... A hero, long absent, has returned, and with
him comes the wrath of the Ultramarines reborn. Roboute Guilliman has
arisen to lead the Imperium out of darkness on a crusade the likes of
which has not been seen since the fabled days of the Emperor.
But never before have the forces of Ruin amassed in such numbers, and
nowhere is safe from despoliation. From the dreaded Scourge Stars come
the hordes of the Plaguefather, Lord Nurgle, and their pustulent eye is
fixed on Macragge. As the Indomitus Crusade rages on, Guilliman races to
Ultramar and a confrontation with the Death Guard.
