Pharos

Cut off from Terra by the Ruinstorm, Imperium Secundus stands as a last point of light while the Warmaster's war spreads across the galaxy. Sanguinius reigns from Macragge, and Roboute Guilliman has persuaded him that the mysterious Mount Pharos on Sotha holds the key to mankind's survival.

The Night Lords, the pitiless Legion of Konrad Curze, have been watching from the shadows and are ready to launch their long-planned assault on the Pharos. The battle that follows pits the Ultramarines against the Night Lords over a device whose true nature nobody fully understands. Guy Haley's first full-length Horus Heresy novel, the thirty-fourth in the series.
