Quick recap
A few years later, Holden is still a prisoner on Laconia, and Naomi leads a resistance scattered across the systems. Avasarala dies. Duarte, set on striking the entities that killed the gate builders, tests a weapon through a gate, collapses a neutron star into a black hole and destroys the Tecoma gate. The entities strike back at every connected system, wiping out Medina Station and a warship. Bobbie dies destroying the Tempest. Elvi Okoye studies what the builders left behind, and Teresa, Duarte's teenage daughter, starts to doubt her father. Naomi leads the strike on Laconia's alien shipyards, and Teresa helps end the standoff.
