Soulbound: Warhammer 40,000 (Unabridged‪)‬

On Delephron, an immense mag-train hurtles through desert. Within its metal confines there lies a hidden message, one that could bring the Raven Guard into such ill repute it would risk its very survival. 

Only the Shadowmasters, the finest of the Chapter’s elite, have the skill to infiltrate the high-speeding mag-lev and extract the message before their presence is known. But dark forces stir against them, servants of the Plague God intent on their own fell purpose. 

And who is the Inquisitor Bledheim, and what could he possibly know to inflict such a deadly blow to the sons of Corax?
