A thousand worlds have opened beyond the gates, and the greatest migration in human history is underway. As colonists stream outward, the old power structures of the solar system begin to strain and crack — ships vanish without a trace, private armies gather in the dark, and something long buried starts to stir.
For the first time in years, the crew of the Rocinante is apart. With their ship laid up for repairs at Tycho Station, each of them turns to unfinished business. Holden stays behind to see the work done. Naomi returns to the Belt and the life she left behind. Amos travels to Earth to bury a piece of his past. Alex goes home to Mars to face what he abandoned there.
Scattered and out of contact, none of them grasps how fast the ground is shifting beneath the whole system — or that the sins of the past are about to come due, all at once. What begins as four separate, personal journeys collides with a threat larger than any of them saw coming.
The fifth novel of The Expanse turns inward on its own characters, giving the Rocinante's crew their own histories and reckonings even as the solar system tips toward its most dangerous hour.
