For the First Time, Again - Sylvain Neuvel - Bog

The epic closing chapter in the trilogy. Aster is the last of an alien race called the Kibsu. But she doesn't know this and she 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.
