Jim Holden is XO of an ice miner making runs from the rings of Saturn to the mining stations of the Belt. When he and his crew stumble upon a derelict ship, The Scopuli, they find themselves in possession of a secret they never wanted. A secret that someone is willing to kill for - and kill on a scale unfathomable to Jim and his crew. War is brewing in the system unless he can find out who left the ship and why.
Detective Miller is looking for a girl. One girl in a system of billions, but her parents have money and money talks. When the trail leads him to The Scopuli and rebel sympathizer Holden, he realizes that this girl may be the key to everything.
Holden and Miller must thread the needle between the Earth government, the Outer Planet revolutionaries, and secretive corporations - and the odds are against them. But out in the Belt, the rules are different, and one small ship can change the fate of the universe.
On Ganymede, breadbasket of the outer planets, a Martian marine watches as her platoon is slaughtered by a monstrous supersoldier. On Earth, a high-level politician struggles to prevent interplanetary war from reigniting. And on Venus, an alien protomolecule has overrun the planet, wreaking massive, mysterious changes and threatening to spread out into the solar system.
In the vast wilderness of space, James Holden and the crew of the Rocinante have been keeping the peace for the Outer Planets Alliance. When they agree to help a scientist search war-torn Ganymede for a missing child, the future of humanity rests on whether a single ship can prevent an alien invasion that may have already begun . . .
