Quick recap
Avasarala blockades the Ring, but Belter settlers have already landed on Ilus, a planet full of alien ruins. She sends Holden as her envoy to referee the fight with the company Royal Charter Energy, whose security chief, Murtry, refuses to share the planet. Holden wakes up the ancient structures, and the planet answers with lightning, a tsunami and a parasite that blinds the settlers. Murtry tries to kill Holden, and Miller leads him to an artifact that shuts down Ilus's technology. The settlers choose to stay. On Mars, Bobbie gets tangled up with smugglers; Gao beats Avasarala in the election; and in the Belt, Marco Inaros kills Ashford and launches stealth asteroids at Earth.
