About the Book

As the protomolecule crisis deepens and a new, more powerful hybrid creature emerges on Ganymede, Holden and his crew are drawn into a political and military confrontation that spans the solar system, joined by a Martian marine and a UN politician fighting to find a missing child. The second Expanse novel expands the cast and stakes while deepening the series' political complexity. Propulsive, emotionally grounded, and structurally tighter than its predecessor.
