In the explosive conclusion to the Codex Antonius trilogy, the fate of humanity hangs in the balance as ancient alien intelligences and galactic empires collide.

Marcus Antonius Cordus, Consul of the Roman Republic, faces his greatest challenge yet. With the Zhonguo Sphere poised to invade and an insidious alien presence manipulating events from the shadows, Cordus must risk everything on a desperate mission to an alien homeworld. There, he'll confront the true nature of the Muses and attempt to end their influence over humanity forever.

But he's not the only one with everything to lose:

Aquilina Servilia, haunted by her mother's murder, must choose between vengeance and saving the Republic she's sworn to protect.

Deshi Ku, exiled prince of the Zhonguo, races to stop his Muse-controlled brother from plunging the galaxy into war.

Dariya, a former slave turned starship captain, faces the destruction of everything she's built as she fights to save the man who gave her a chance at freedom.

As battles rage from Rome to the stars, unlikely allies must band together to face threats beyond imagination. In a universe where gods walk among mortals and ancient intelligences pull the strings of empires, can humanity forge its own destiny?

Don't miss Muses of the Republic, the thrilling conclusion to Rob Steiner's genre-bending space opera that blends Roman history, cutting-edge science fiction, and pulse-pounding action. Perfect for fans of The Expanse, Dune, and Old Man’s War.
