Infinite Dark — Page Morgan

He was supposed to stay away...After surviving an alien invasion that nearly destroyed New York City, Penelope Simmons is beginning to accept the truth: Rowan, the Volkranian she fell in love with during the attacks, is gone for good, and it's about time she and the rest of humankind adjusted to Earth's newest inhabitants.But then, they came for her...An old enemy has tracked the Volkranians to Earth, hunting for the baby prince stolen from them long ago-Rowan-and they will stop at nothing to reclaim him. The Inoori know he will do anything to save Pen and hundreds of abducted human prisoners from a fate worse than death, and that is exactly what Pen fears too.Falling love with an alien was never going to be easy, but as Pen hurtles through the universe, she'll have to choose who to save-and if she can survive her choice.
