Storm of Damocles

As the Imperium and the T'au Empire clash across the Damocles Gulf, a Deathwatch kill-team led by a White Scars veteran uncovers a devastating new piece of xenos war technology that could turn the campaign. To counter it, the Deathwatch captain must call on his former battle-brothers in the White Scars, testing old loyalties. The story balances brutal frontier warfare with the strain of a warrior caught between two brotherhoods.
