Tiamat's Wrath

Humanity has built an interstellar empire in the alien ruins, but mysteries and threats grow deeper. Tiamat's Wrath finds the crew of the Rocinante fighting an underground war against a nearly invulnerable authoritarian empire, while James Holden is a prisoner of the enemy. At the heart of the empire, Teresa Duarte is ready to take on her father's godlike ambition, and Elvi Okoye searches for the nature of a pre-human genocide. Courage and ambition won't be enough, as a battle looms that humanity can only lose. The eighth book in The Expanse series, now a Prime Original series.
