"So I have a sister?" was Aires's response when Lucia and Diego told her of Luna's upcoming visit. "You have a sister," Lucia answered. With this revelation, nineteen-year-old Aires Caredana was to welcome her long-lost sibling to her family home. Her sister was gravely ill, and no one knew how to treat her. Over two hundred years had now passed after the construction of the villa in which the Caredana family lived. The villa and, adjacent to this, a lake, were well renowned. Nobody knew whether to believe or dismiss accounts of healing from this water. They were abundant and could easily be heard. Luna would soon be there. She knows absolutely nothing of this reputed river. Aires was preparing to leave and had little time to stay with her sister, Luna. Their parents were sure Luna would not be long with them. A perhaps two-acre river just could be the resolution to an issue, which had plagued this family for eighteen years.
