Continuing the brutal reality started in the first book, this one deftly interweaves a political scheme where Horus is injured to the precipice of death, brought to a religious environment for healing, recovers, then totally reverses his meaning for universal conquest from man-controlled peace to total annihilation of all not deemed worthy. This conveniently includes usurping the Emperor and taking his place. I enjoyed how Chaos was injected into this and how the Astartes Mournival was basically split in two. This novel basically sets up an arena of future conflict for all parties, and sets the galaxy on a path for destruction. Told you this was pure geek...RTYB.
