The epic saga of Ragnar Blackmane continues with this explosive tale set on the holy planet of Terra, where the ancient navigator house of Belisarius has long been allied with the mighty Space Wolves. In return for the means to navigate the treacherous warp, the Space Wolves provide an honour guard for the Patriarch of the house. But as Ragnar takes up this assignment, he uncovers a plot that reaches into the very depths of the Imperium and perhaps even to the God-Emperor himself!
