Sally Jackson knew her son would be hunted his entire life for his heritage and power, but she would not see him enter this terrifying new world unprepared. One rather desperate favour later, and we find Percy Jackson at twelve years old, attending Yancy Academy, having been training with his Uncle John and his cousins Sam and Dean for six years.
Percy is seven when it appears. The Soul-Scar. The one he can't hide. - Everyone has a soulmate, even if not everyone believes in them. This is one thing. Every now and then, though, the fates bind together two people who share a great destiny even further. This is entirely another.
