Slaves to Darkness

by John French · The Horus Heresy series

The Warmaster's forces gather strength as the traitor legions descend into the darkness they have chosen. As Horus consolidates his power and marches toward Terra, the corrupted primarchs and their warriors embrace the gifts of Chaos, becoming something far beyond human—and far more monstrous.
