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.

Imagine everything you thought you knew about human progress was wrong. What would you do? Mia is not sure what she is, but she isn't human. Smarter, stronger than her peers, all she knows are the rules: there can never be three for too long; always run, never fight.  When she finds herself in Germany, 1945, she must turn the Nazi's most trusted scientist with an offer: abandon the crumbling Nazi party, escape Germany with your life, come to work for the Americans building rockets. But someone is watching her work. An enemy who's smarter, stronger, decidedly not human and prepared to do anything to retrieve something ancient that was long lost. If only she had any idea what it was . . .

Over 100 generations, Mia's family has shaped Earth's history to push humanity to the stars, making brutal, wrenching choices along the way.

And now Mia finds herself about to help launch the first people into space. She can't take them to the stars, not quite yet. But with her adversary almost upon her, and with the future of the planet at stake, it's becoming clearer that obeying the First Rule is no longer an option.

For the first time since her line's first generation, Mia will have to choose to stand her ground, knowing that the overwhelming odds mean that she risks not only her bloodline, but also the future of the human race.
