Angel Exterminatus is one of Graham McNiell's best Horus Heresy novels to date. The main plot of this novel is the teaming up of Fulgrim and Perturabo as they venture into the Eye of Terror to discover some Eldar super weapons. back stabbing and lies ensue between the brothers while a force of Iron Hands seeks to disrupt there venture.
