Complete story — includes the ending
Bobbie forces Captain Martens to reveal Jules-Pierre Mao's protomolecule technology project. A demonstration of it caused the Ganymede Incident and triggered the battle in orbit. The technology is now for sale. Bobbie takes the information to Avasarala at the UN and requests political asylum. Mao offers to explain everything to Avasarala if she meets with him outside of UN control. She accepts over Cotyar's objections. The research team aboard the UNS Arboghast lands a probe on Venus. They see a massive protomolecule structure before the probe fails. Alex uses a Gravity slingshot to sneak the Rocinante past the MCRN blockade of Ganymede. Holden and crew explore the old part of the station. They find guards and scientists having a pizza party. After Prax starts a gun fight, the survivors barricade themselves in a back room. Holden and Prax realize the protomolecule monsters are actually Belter children with genetic peculiarities and deliberately infected with protomolecule. The fate of Mei is unclear. Most of the enemy is killed by a protomolecule monster, but a dying scientist says there are plenty more out there. The party splits. Naomi and Amos evacuate people off Ganymede, while Holden, Prax, and Alex hunt the protomolecule monster on the surface.
