The Arrival

Losing his family and several friends to an attack waged by the Camadors, a race of aliens bent on chaos and taking over the world has been hard on Sorrin, leading the warrior to become hardened and single minded where he was once much more friendly and easy going. When he finds out that the Camadors are planning to take their reign of terror to Earth, he follows, arriving just in time to find that humans are being taken prisoner and that the Camadors have something planned for the planet. His mind isn't on saving the humans, but getting his revenge, and so he attacks their floating city, but winds up getting captured. 

Sorrin finds himself in a cell with a human woman, and when she clings to him, he takes her with him when he escapes, figuring he can use her for information at least. But there is much more to this woman than meets the eye, and more to this mission than he ever expected. Sorrin will have to put his revenge to the side in order to protect a planet and the people who have come to mean something to him.
