Age of Darkness

The sixteenth Horus Heresy book is an anthology of nine short stories, edited by Christian Dunn, set in the years after the Dropsite Massacre on Isstvan V as Horus begins his long campaign towards Terra. Suspicion and paranoia spread across the Imperium, and the stories range from a primarch preparing for the worst to a loyal Space Marine standing against his own traitor Legion. Contributors include Dan Abnett, Graham McNeill, James Swallow, Aaron Dembski-Bowden and Gav Thorpe.
