The Rocinante arrives at their true destination, an asteroid at coordinates given by Fred Johnson and discovers the Anubis, the stealth ship that destroyed the Canterbury. It's empty aside from a mysterious organic substance that is covering the ship's reactor. They scuttle the stealth ship, then head to Eros to find a survivor of the Scopuli codenamed Lionel Polanski, who escaped the Anubis on its shuttle. Miller is also tracking down Polanski, identifying her as Julie Mao. Arriving at Eros, Holden and his team are ambushed at the hotel where Polanski is staying by a UN black ops team (signaled by Kenzo, and authorized by Errinwright), but are saved by Miller. After joining up, Holden's team and Miller go to meet Julie Mao only to find her dead, infected by the same substance from the Anubis.
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.
