Warhammer 40k - Legacy of Caliban Novel - Master of Sanctity by Gav Thorpe

The Legacy of Caliban echoes down through the ages, and the secretive mission of the Dark Angels continues. Interrogator-Chaplain Asmodai sees treachery and deceit everywhere he turns – while this serves him well in his hunt for the Fallen, it also strains the Chapter’s relations with their Imperial allies. With their true quarry now seemingly within their grasp, Brothers Annael and Telemenus find themselves at the forefront of a new operation that could shake the Imperium to its very core.
