With 1300 new worlds within reach, a new interplanetary "land rush" has begun. The UN charges the crew of the Rocinante to settle a land dispute on its new colony world "New Terra". Meanwhile, the OPA begins transitioning the Behemoth to become outpost and gatekeeper to humanity's new frontier.
Two hundred years in the future, in a fully colonized Solar System, detective Josephus Miller, born in the asteroid belt, is given the assignment to find a missing young woman, Julie Mao. Joining his task is James Holden, formerly first officer of an ice freighter who is involved in an incident caused by the tense relationship between Earth, Mars and the Belt. Soon the two find out that the missing woman is connected to a vast conspiracy.
