Broken by the destruction of their home world Prospero at the hands of the Space Wolves Legion, Magnus the Red and the Thousand Sons retreat into the Eye of Terror. Is there any way for the Crimson King to rise again? After the razing of Prospero, Magnus the Red spirited the Thousand Sons away to the Planet of the Sorcerers, deep within the Eye of Terra. Removed from the concerns of the galaxy at large and regarding the Warmaster's unfolding Heresy with cold detachment, Magnus has dedicated his hollow existence to the preservation of all the knowledge once held in the great libraries of Tizca, should mankind ever seek such enlightenment again. But his sons can see the change in their primarch - he is a broken soul, whose mind and memories are slipping away into the tumult of the warp. Only by returning to the scenes of his greatest triumphs and tragedies can they hope to restore him, and allow the Crimson King to be crowned anew by the Ruinous Powers. * The Horus Heresy is Black Library's flagship science fiction series, with worldwide sales of over three million copies. * Graham McNeill is a New York Times bestselling author and a winner of the David Gemmell Legend Award for his Warhammer fantasy novel Empire. * Follows on from Graham McNeill's previous Horus Heresy novel about Magnus the Red, A Thousand Sons, which has sold over 100,000 copies worldwide.
