Paradox, book 3: Heaven's Queen
Rachel Bach2014

From the moment she took a job on Captain Caldswell's doomed ship, Devi Morris' life has been one disaster after another: government conspiracies, two alien races out for her blood, an incurable virus that's eating her alive.

Now, with the captain missing and everyone -- even her own government -- determined to hunt her down, things are going from bad to impossible. The sensible plan would be to hide and wait for things to blow over, but Devi's never been one to shy from a fight, and she's getting mighty sick of running.

It's time to put this crisis on her terms and do what she knows is right. But with all human life hanging on her actions, the price of taking a stand might be more than she can pay.
