From New York Times best-selling author James S. A. Corey...
Before his trip to the stars, before the Rocinante, Amos Burton was confined to a Baltimore where crime paid you or killed you. Unless the authorities got to you first.
Set in the hard-scrabble solar system of Leviathan Wakes, Caliban's War, Abaddon's Gate, and the upcoming Cibola Burn, The Churn deepens James S. A. Corey's acclaimed Expanse series.
