As he builds his empire, he'll find that not all enemies are what they seem. An invading army powered by wild magic and captured spirits will face him down, but his own people are busy, too, and their new technologies will bridge the worlds between science and sorcery. Can they create weapons in time? Either way, Troy and his queens will ride forward into war once again, but this time there's a lot more at stake, because the enemy wants Helen, and they’ll do whatever it takes to have her. Join Troy as he fights for Helen, and his people, and nothing less than the fate of his entire world.
