Blood of Asaheim is a Black Library novel by Chris Wraight, the first in a new series featuring the Space Wolves. It was published in April 2013.
After half a century apart, in service to the Deathwatch and the Chapter, Space Wolves Ingvar and Gunnlaugr are reunited. Sent to defend an important shrine world against the plague-ridden Death Guard, the Grey Hunters clash with the pious Sisters of Battle, who see the Space Wolves as little better than the enemy they fight. As enemies close in around them and treachery is revealed, Gunnlaugr and his warriors must hold the defenders together – even as hidden tensions threaten to their the pack apart.
