Experience the Galaxy’s Darkest Hour

The Horus Heresy reaches its most devastating turning point as the Warmaster’s treachery explodes into full-scale civil war. What began as a covert act of betrayal has been exposed, but the true horror of Horus’ plans remains hidden from those who dare to oppose him. The mightiest force ever assembled marches toward what they believe will be swift justice, unaware they are walking into the most catastrophic trap in Imperial history.

Why This Novel is Essential Reading

This is the most comprehensive and unflinching examination of the Dropsite Massacre ever written. While you may think you know what happened on Isstvan V, author John French unveils layers of treachery and horror that will fundamentally change your understanding of this pivotal battle. The betrayal cuts deeper, the losses strike harder, and the consequences reshape the entire galaxy.

The Story That Changed Everything

When Horus’ rebellion is discovered, the Emperor’s response is immediate and overwhelming. Rogal Dorn and Malcador the Sigillite marshal an unprecedented force of Space Marine Legions and their Primarchs to crush the Warmaster’s insurrection before it can spread. This mighty armada represents the full might of the Imperium, sent to deliver swift retribution and restore the dream of the Great Crusade.

A Trap of Unimaginable Scale

The loyalist forces arrive at Isstvan V expecting to be the instruments of justice, ready to purge the traitors and restore order. Instead, they face a betrayal so profound it will shatter the Imperium forever. The heroes who land on that cursed world will not deliver a massacre but suffer one, and those few who survive will emerge into a galaxy transformed by darkness.

The End of an Age

On the killing fields of Isstvan V, the last hope for reconciliation dies. The unity of the Imperium crumbles to dust, and the dream of the Great Crusade ends in blood and treachery. What emerges from this catastrophe is a new era defined by endless war and suspicion.
