Horus Heresy: Book 3 - Galaxy in Flames

The opening trilogy reaches its devastating climax. Ben Counter's Galaxy in Flames is the book where the Horus Heresy stops simmering and finally boils over — and where the true scale of the betrayal becomes horrifyingly clear.

What it's about

A recovered Horus, now fully turned, lures the Imperium's finest into a trap that sets the galaxy alight and forces the loyalist Space Marines into an impossible fight for survival. Counter brings the opening trilogy to a brutal, decisive close, setting up everything the rest of the Horus Heresy saga builds on.

Best for

• Readers finishing the opening trilogy after Horus Rising and False Gods
• Anyone who wants the moment the Heresy truly begins
• Horus Heresy collectors building the saga in order

This is the one where the betrayal stops being a threat and becomes a war — essential reading before the wider saga unfolds.
