Overview and Impressions:
This book in the Horus Heresy series features the Ultramarines primarch Roboute Guilliman trying to salvage what was left of the Imperium as civil war raged between Horus's Chaos traitor legions and the Imperial loyalists.
However, the Five Hundred Worlds are isolated from Terra due to warp storms. Guilliman tries to rebuild civilization as refugees from all over the galaxy flee to his realm. Assassins and primarchs also descend on Macragge. There are also xenos led traitors and all sorts of plot twists as the novel progresses. The reader also meets an insane Vulkan and Lion el Johnson, primarch of the Dark Angels who come to Macragge on a mission to insure Guilliman doesn't betray the Emperor in his attempt to save the Imperium.
Overall, a good read. Recommended for WH40K fans.
