The Primarchs

The twentieth Horus Heresy book, edited by Christian Dunn, gathers four novellas, each centred on one of the Emperor's primarch sons: Fulgrim, Ferrus Manus, Lion El'Jonson and Alpharius of the Alpha Legion. The stories are by Graham McNeill, Nick Kyme, Gav Thorpe and Rob Sanders, and each adds depth to a primarch who appears across the wider series.
