Unaware of the wider Heresy and following the Warmaster's increasingly cryptic orders, Roboute Guilliman returns to Ultramar to muster his Legion for war against the orks massing in the Veridian system.

Without warning, their supposed allies in the Word Bearers Legion launch a devastating invasion of Calth, scattering the Ultramarines fleet and slaughtering all who stand in their way. This confirms the worst scenario Guilliman can imagine - Lorgar means to settle their bitter rivalry once and for all. As the traitors summon foul daemonic hosts and all the forces of Chaos, the Ultramarines are drawn into a grim and deadly struggle in which neither side can prevail.

My favourite Horus Heresy book. Love the buildup to the action and the brutally no-nonsense narration.

Favourite of mine by some distance. The second person narration is weird but works quite well here.

Best in the series so far

Fascinating story, a great look at the Ultramarines and how their long standing rivalry with the Word Bearers gained such traction. Interesting to see Gulliman in such a truly perilous situation and how he operates to remedy it.

Great book

Fantastic to listen to

I never really liked the Ultramarines as they're the poster boys for 40k but this had changed my mind... I may even paint some boys in blue...
