The Long Night: The Horus Heresy Series (Unabridged‪)‬

The Dark Angels and the Night Lords fought one another to a bloody stalemate during the Thramas Crusade and, though the Lion eventually claimed victory, it left both Legions scattered and under-strength. Jago Sevatarion, First Captain of the Night Lords, languishes in a gaol cell in the heart of Ultramar. Far from a spent force, the Night Lords must consider where their loyalties lie, and what path they will take in the days and months to come.
