Quick recap
Earth and Mars go to war, pushed by Errinwright. On Io, the crew finds the lab where Strickland turns children into weapons, captures Mao and saves Mei, while the evidence against Errinwright goes public and he's arrested. The protomolecule leaves Venus and forms a Ring beyond Uranus. Ships from Earth, Mars and the Belt head there, and Holden starts seeing Miller, who calls himself an Investigator. Inside the Ring, the alien station locks every ship in place. Ashford tries to destroy it with a laser, but Holden, Naomi and Drummer shut down the Behemoth's reactor. The station calms down and opens more than a thousand gates to other systems.
