Ary never knew who his real father was, but that was alright as he was surrounded by a loving family. Sandy, on the other hand, couldn't get Ary's father out of her mind, despite focusing on her work as Captain of the S/S Asteroid, and her almost-marriage to Kyle.
When the Asteroid is called into the galactic divide, Ary and his almost-sister, Kit are deposited on a spacebase for vacation. There, they will be met by a strange man, who will take them across the stars to the meet the one who holds the key to Ary's future.
