Following the events in Caliban’s War, the protomolecule shoots itself off into the far reaches of the Solar System, well beyond the orbit of Neptune. It forms a large ring. As it turns out, the ring is a gate to another place far away from the Sun. Mars, Earth and the Outer Planets organize expeditions to study the gate. Meanwhile, the sister of Julie Mao, the mysterious woman from Leviathan Wakes, has decided to disgrace James Holden, who along with the crew of the Rocinante, is also on his way to the gate. Needless to say, things rapidly go south, with the large multinational fleet of research and warships trapped beyond the gate in a mysterious “slow zone” which limits the speed of ships. And then things go south some more as internal fighting breaks out between various factions.
Just as in the previous books, the story is told via viewpoint characters, with excellent characterization. There is deep examination of motivation and personality without it getting in the way of the action. In some ways, the book, just like its prequels, reads like an action blockbuster, especially the last third of it. But it is deeper than that, showing the authors’ insight into human nature, society and politics. The world is granular and consistent, with little things like how Belters and Earthers think alike fully developed and really affecting the actions of the characters. The stakes are high and the situations often desperate. I couldn’t stop reading because the authors kept putting our heroes in situations that seemed impossible while the fate of humanity was on the line; a real skill.
Caliban’s War is set one year after the events of Leviathan Wakes. The crew of the Rocinante is on contract from the Outer Planets Alliance to hunt pirates. Meanwhile, on Ganymede, the daughter of research botanist Praxidike Meng is abducted just prior to an unexplained assault by both Mars and Earth fleets. Turns out that the deadly protomolecule is loose again. But who set it loose? The Solar System is on the verge of war. Once again, the Rocinante finds itself in the center of things.
This book was fully as good as the first; perhaps even a touch better. The action is excellent and the prose beautiful. The attention to detail regarding the effects of living in the Asteroid Belt or on a moon of Jupiter are wonderfully thought out. For example, Belters nod with one hand since a head nod is not often visible when wearing a helmet. Both the old characters and the new ones stand out in their characterizations, with well-written arcs propelling them forward in the story.
A few hundred years from now, humanity has colonized the Solar System. Mars and Earth (the “Inner Planets”) are the developed juggernauts of society, with Earth crowded by a population of thirty billion. The rest of humanity lives on various moons and asteroids (the “Outer Planets”), hollowed out or domed for habitation. Tension between the Inner Planets and the fringe has been constant for centuries, with the fringe being gouged on taxes and kept cowed by the massively powerful Mars-Earth combined navies.
The story is told from the viewpoint of two characters, freighter officer Holden, born on Earth, and Ceres police officer Miller, born and raised on Ceres itself. Holden’s ship is attacked for (initially) undetermined reasons and along with a few other survivors he is now a fugitive from powerful interests. Miller is asked to investigate the disappearance of one Juliette Andromeda Mao, scion of a rich family who left the fold to hang with the semi-terrorist Outer Planets Alliance, a group dedicated to independence from the Inner Planets. Miller’s search soon leads him to an encounter with Holden, as they both try to figure out who is inciting a shooting war between the Outer Planets and the Inner Planets. More importantly, what is the terrible plague that found Julie Mao; who is trying to use it and for what purpose?
The plot moves along quickly, with kick-ass action scenes worthy of a blockbuster movie. Miller’s slow descent into madness is contrasted with Holden’s transformation from naive boy scout to cynical player. The divergence of Inner Planet and Outer Planet society is finely described with tidbits sprinkled throughout the book; a story of frontier society trying to define itself. The supporting cast is wonderfully fleshed out, avoiding stereotypes and developing relationships realistically. The story itself twists in unexpected directions, with a grandiose “couldn’t see that coming” ending. Great space opera!
