Janus. Future Possible Saga, #5

It has barely been a year since Mankind took back our world from invaders. Earth has been left damaged and torn. We are practically extinct as a race. Now, Mankind has begun the job of rebuilding. John Smith XXXIV of Aretu was a soldier before his queen asked him to serve as ambassador to Earth, and he is now out of his element. Restricted in his position to carry a weapon, he has no means to defend himself or his adopted son from those who would rather see "the alien" dead.
Jenifer with no last name she'll claim is a gun for hire, and answers to no one but her own common sense. She first refused the "job" of protecting the Areth ambassador, but a glimpse at the heart of the man convinced her to take the responsibility. As if the Sorracchi weren't enough of an enemy, Earth has home-grown problems called Xenos - humans who want to purge the Earth of all alien influence.
Many hide behind masks, and some want John dead. In Part Two of the Future Possible Saga, Earth moves forward but no longer alone. Our knowledge of the galaxy has grown beyond the limits of our own system and we now have strong allies in the Defense Alliance, a coalition of advanced planets who welcome Earth into their ranks. Another fight is coming. Will we prevail?
