Claw your way out of the radioactive ash, bear witness to the tragic final hours of a fractured world, and discover what remains when the galaxy's greatest war leaves an empire in ruins.

The Horus Heresy: Siege of Terra: Flames of Betrayal is a gripping, 384-page science fiction anthology that explores the chaotic, immediate aftermath of the battle for humanity's homeworld. Released in July 2026 by Games Workshop's Black Library, this volume marks the definitive compilation that wraps up the final outstanding threads of the monumental Siege of Terra sequence in mass-market paperback form. Featuring contributions from the franchise's most celebrated authors—including Dan Abnett, Aaron Dembski-Bowden, and Guy Haley—this book serves as a vital bridge between the bloody climax of the Heresy and the grim, dark reality of the unfolding "Era of Ruin".
