Warhammer 40,000: Deus Encarmine (20th Anniversary Edition)

On the remote world of Cybele, the Adeptus Astartes of the Blood Angels Chapter are fighting a losing battle against the forces of Chaos. Yet as Battle-brother Arkio leads a counter-attack that has the enemy reeling, there is sudden talk that this is a holy sign. Does the spirit of Sanguinius indeed bless Arkio, or is the turmoil for the Blood Angels just beginning?
