The third instalment of the Space Marine Conquests series, War of Secrets sees Phil Kelly explore the integration of Primaris Marines into the ever-secretive, antagonistic Dark Angels Chapter. In battle against the t’au on the industrial world of Saltire Vex, Lieutenant Xedro Farren and his Primaris brothers find the Dark Angels under Interrogator-Chaplain Zaeroph to be less than welcoming. It’s not long before Farren sees hints of an ulterior mission and another shadowy enemy, whom Zaeroph will do anything to catch. Meanwhile within the ranks of the t’au a separate conflict is brewing, and loyalties on both sides are questioned.
