Complete story — includes the ending

Everyone boards the Behemoth with all weapons seized by the OPA. Holden is believed to be insane and Clarissa wears an injection system to impair her abilities. She is locked across from Holden without him knowing who she is. Anna tells her all she can hope for now is forgiveness. Holden tells Ashford the beings that created the Rings and protomolecule were somehow killed and used Rings to destroy planetary systems, attempting to save themselves. Drummer builds herself mechanical legs with help from Naomi, whom she later reunites with Holden. Clarissa can hear Holden's torment as he tries to get Miller to tell him what to do next. Amos takes a liking to Anna. A tech from Earth has the idea to send a damaged skiff with a nuclear missile to try and weaken the field blocking immobilizing ships and blocking the laser communication to the outside world. In response, the station begins charging energy. Ashford realizes the station intends to destroy the entire solar system and convinces the leaders of Earth and Mars to destroy the Ring with the laser, saving humanity at the cost of marooning everyone inside the Ring.
