Nemesis Games

The Rocinante is down for long-term maintenance after the events of Cibola Burn. Three crew members decide to take care of some personal business during the down time. Amos Burton heads to Earth when he learns someone important from his past there has died, both to pay his formal respects, and to make sure no foul play was involved. Alex Kamal heads to Mars in the hopes of getting closure with his ex-wife and to see Bobbie while there. Naomi Nagata heads to Ceres station, when she receives a message that her son Filip is in trouble. While Jim Holden supervises repairs to the Rocinante, he is enlisted by Monica Stuart to investigate disappearing colony ships.

Facing collapse by the exodus of colony ships through the rings, militant factions of the OPA coalesce into a Free Navy and simultaneously wreak havoc on Earth by dropping asteroids onto the surface, and subsequently attempting to kill the Martian Prime Minister and Fred Johnson. Amos survives the attacks on Earth, frees Clarissa Mao and escapes to Luna with her help and the help of Baltimore organized crime acquaintances from his old life. Alex meets Bobbie on Mars and they investigate missing Martian military equipment and ships, which leads them into the middle of the assassination attempt on the Prime Minister.
