Synopsis

The fall of the Laconian Empire leaves thirteen hundred solar systems newly free, but a long-dormant enemy is awake once more. Elvi Okoye’s mission in Adro seeks answers about the gate builders and their destruction, while Colonel Aliana Tanaka pursues Duarte’s missing daughter and Duarte himself.

On the Rocinante, James Holden and his crew face the challenge of building a future from the ruins of the past. With forces threatening all human life, Holden and unlikely allies uncover a final chance to unite humanity, though the cost of victory may be worse than defeat.
