Alone in a New World — Sherry Derr-Wille

As a child of four, Marco is all alone in the world. With only his mother in his life, her death prompts the authorities to send him to Henderson Ranch for boys. At the age of eighteen, he is sold into slavery to a ranch in Mexico. Two years later, he is recued and reunited with his childhood friend, Christopher. At his friend's insistence he modernizes his name to Mark and embarks on a journey that will bring him full circle back to Henderson Ranch, now called Resurrection Ranch. On his journey, Mark finds previously unknown family and love with one of the alien nurses, Kara, all of whom are willing to journey with him into the future at Resurrection Ranch.
