December - The Souls of the Stars Saga, #1

Perfect for fans of Star Trek. Over a hundred years in the future, Earth has fallen under the invasion of a hostile alien race-the Drevi. Half the human population has been captured as specimens, while the rest are fighting for their lives in a resistance movement that has suffered more defeats than achieved victories. Ted Anderson, a 42-year-old information specialist from the American States, thought nothing could save him from his new life.
In spite of being an aide to a leading Drevi scientist who treats him well, he is reminded every day what he truly is. A specimen. An Inferior with no future. Then he crosses paths with two strange new aliens, their assignment to investigate and aid their government in determining whether it should intervene to help free a subjugated humanity. And all of Ted's dreams come true. He matters. He's going to travel to a distant world to advocate on behalf of his people.
And most of all, he is free again. Now Ted is drawn into a dangerous conflict to save all he knows and loves. But the fate of more than just humanity might rest on his shoulders.
