Book 8 in the Warhammer 40,000 Megaseries, Dawn of Fire.

As the Indomitus Crusade rages on, Inquisitor Rostov discovers vital intelligence that could reveal the plan of the notorious Hand of Abaddon, and hastily gathers together those loyal to his cause. Defending the Anaxian Line, Ultramarines Lieutenant Ferren Areios uncovers a dread vision that has ties to the mission of an old ally. Meanwhile, Magda Kesh campaigns alongside the 84th Mordian. Though she refutes her fate as something more than a mere soldier, is she truly touched by the Emperor?

Despite a fractious alliance, the Hand's scheme is reaching culmination. Amidst the infighting, Tharador Yheng yearns to be free of her master Tenebrus' shadow and claim her destiny. But another acolyte has embarked on his own path, the Red Corsair Graeyl Herek. Both vie for the favour of the Dark Gods, and the means to harness an ancient evil that could reshape the war between the Imperium and Chaos.
