Cibola Burn
The gates opened by the alien Ring have unlocked a thousand new worlds, and humanity is racing to claim them. The first lies just beyond the threshold: a planet the Belter refugees who settled it call Ilus, and the corporation that holds its legal charter calls New Terra.
The settlers came first, illegally, and built a hard life mining the world's riches. Now a company survey ship arrives to take formal possession — and when first blood is spilled, a standoff hardens into open, ugly conflict, with scientists and families caught between armed settlers and corporate security.
James Holden and the crew of the Rocinante are sent to keep the peace on a world neither side will surrender. But Ilus is not the empty frontier it appears to be. Beneath its surface lie the silent remains of the civilization that built the gates — and something in that ancient machinery is beginning to wake.
The fourth novel of The Expanse trades the corridors of the inner system for a raw, western-tinged story of survival, greed, and the true cost of the frontier.
Captain of the Rocinante, sent as the UN's reluctant mediator to a colony world on the brink of open war.
A Belter settler and father caught up in the violence, torn between his family and the consequences of a desperate act.
An idealistic corporate biologist studying Ilus's alien ecology as catastrophe closes in.
The corporation's ruthless head of security, who answers every provocation with lethal force.
A company security officer stationed in orbit, and once a lawman in the Belt.
While the narrative on the planet Ilus reaches a definitive conclusion, the book serves as a critical bridge that establishes long-term geopolitical and technological developments for the remainder of the series. Readers who skip it will miss essential context regarding the expansion of the gate network and the evolving status of the protomolecule.
The fourth season of the television series adapts the primary plot of this book, but it also incorporates characters and storylines from later novels and novellas to expand the scope of the show. Consequently, the television version introduces political developments that do not occur until the subsequent books in the series.
