Artemis

Artemis McIvor is a thief, a con-artist, and a stone cold killer. And she's been on a crime-spree for, well, for years. The galactic government has collapsed and the universe was hers for the taking.
But when the cops finally catch up with her, they give Artemis a choice. Suffer in prison for the rest of her very long life, or join a crew of criminals, murderers, and traitors on a desperate mission to save humanity against an all-consuming threat.
Now, Artemis has to figure out how to be a good guy without forgetting who she really is.
