Delve into the character and motivations of Lion El’Jonson’s closest friend – and bitterest foe – like never before in Luther: First of the Fallen by Gav Thorpe. The Protector of Caliban embodies the duality at the heart of the Dark Angels, and the story behind his fall to Chaos is one of the most curious in the annals of the Horus Heresy. This classic novel is now coming back to shelves in a new paperback edition.
