When you don't know The Rules it's hard to stay safe. After a traumatic incident, Aster finds that her blood work comes back with some unusual readings. Unsurprising, as she's the last of an alien race called the Kibsu. But Aster doesn't know this. Immediately, Aster finds herself the focus of a hunt, with her mortal enemies, the Trackers, on one side, and the American government on the other. There seems to be nowhere she can run. But help often comes from the most unexpected quarter . One thing is certain.

Whoever finds Aster first will hold the fate of the Kibsu - and our world - in their hands.
