Renegade (Aquila, Book 3)

Following the successful defense of Alamarri and the sudden withdrawal of Hepharion's Chaos Marines, Caius returned to Macragge in time to see the return of his Primarch and receive a new mission from his Captain: find Hepharion and bring him down, no matter the ost, and chase down and secure the remains of the ancient Titan project. At first, resources seem scarce with the Black Crusade taking much of the attention and firepower of the Ultramarines. However, help comes in an unexpected form when an Inquisitor's acolyte appears with an unexpected offer for the men of the Twentieth.

Across the stars, Bahad is called before the Council of Farseers of his Craftworld and desperately pleads his case for his alliance with Caius and his hunt for Hepharion. However, this falls on deaf ears when the Craftworld, concerned about his continued association with the Imperium, orders him into a temporary arrest to await further judgment. While in isolation. plagued by his visions of what shall happen without his involvement, he, too, receives an unexpected visitor: a Harlequin Solitaire with a keen interest on seeing him reunited with his Ultramarine.

As the two friends journey forth, their paths lead them to one another once again and to the planet of Cosperan, home to a Black Templar Crusade and the most recent spot where Hepharion's Warband was spotted. Aided by Deathwatch Squad Ostentia, a wounded squad sent to reinforce the Twentieth, and their Battle Brother Varis, they join Chaplain Marshal Reimar and his fight against the forces of Chaos and aim to strike a blow against Hepharion that he will not soon forget.
