Blazing Sun - The Goddess Maker, #2

Death wasn't the ending. It was the catalyst. Cassius d'Etrius was all too familiar with suffering. After losing his family, his best friend, and his only love, he'd had his fill of it. His sole focus was protecting what remained, no matter the cost, and there was no limit to what he was willing to sacrifice to that end. Even if it meant partnering with a traitor. Six years of brutal training molded him into the model Volandrian nobleman, fit to hold the title of the Duke of Etrius.
Cold and calculating, with instincts that made him a threat to anyone unlucky enough to cross his path, it came as no surprise when he seized control of the Southern Command after only three years under the tutelage of Marquis Genji Kitamura, a move that cemented his position in high society. But when a mysterious woman crosses his path, Cassius can't help but be drawn into her orbit. The decision to follow her leads to answers he never imagined and more questions than he thought existed.
In a dizzying whirlwind of events that push his loyalties to the breaking point, Cassius must decide who to trust. Or who to kill.
