Book 5: Fulgrim
A Horus Heresy novel
As the Great Crusade draws to a close, primarch Fulgrim and the Emperor's Children continue their pursuit of perfection. But pride comes before a fall, and this most proud of Legions is about to fall a very, very long way...
READ IT BECAUSE
Graham McNeill paints a masterly portrait of a Legion brough low by their own hubris. And we see the epic Dropsite Massacre of Isstvan V, and the death of a primarch. Doesn't get much bigger than that.
