My Enemy, My Hostage, My Alien

Fifteen years ago, aliens slaughtered Birdie's entire kin. A strange alien boy appeared. He would secretly bring her food and even took a bullet for her before vanishing from her life forever. Now, having reclaimed her empire through a blood-soaked struggle, Birdie finds that the final survivor pulled from the ruins is none other than a tall, alien heir with pale violet eyes. Just as she is about to execute him, an unexpected turn of events forces her to reconsider.
