The Coalition (Ann Aguirre) Books in Order

The Coalition is part of the wider science-fiction setting associated with Ann Aguirre's space opera. It refers to the political and military forces trying to hold together a dangerous interstellar order while war, corporate power, and alien threats keep exposing its weaknesses.

In the Sirantha Jax books, the Coalition is not a distant backdrop. Its policies, secrets, and conflicts affect where people can travel, who is treated as expendable, and how much freedom ordinary citizens have. Jax and her allies often find themselves caught between official power and the people who live outside it.

Space politics has consequences.

This setting includes jump travel, hostile alien forces, remote worlds, smugglers, and factions with competing ideas about security and control. The connected stories work best when readers follow the main Sirantha Jax sequence from the beginning, because the broader political situation grows out of Jax's personal struggle to survive and choose her own loyalties.

Start with Grimspace, then continue through the Sirantha Jax novels in order. Readers who want more from the same universe can also move on to the Dred Chronicles, which explores a prison ship and its own brutal local politics. Expect character-driven space adventure rather than a simple map of good and evil.
