In the dark hive sumps beneath Terra, Chief Librarian Fel Zharost of the Night Lords Legion is being hunted. Having abandoned his insane primarch and brothers many years ago, he doesn’t know what he’s done wrong, but he’s sure he doesn’t want to be captured. What will happen when he discovers that his Legion has fallen into heresy? And where will his loyalties lie? Read it because... Learn the fate of the Chief Librarian of the XIII Legion, former servant of Konrad Curze. The first Horus Heresy Night Lords story from John French is both an insight into changes that have taken place within the XIII Legion over the course of the Great Crusade, and a fascinating glimpse into the underworld slums of ancient Terra itself.
