  Summary

  Warning: Prequel to HOO

  Anyone ever wonder what was Jason doing while Percy Jackson was dealing with Titans, Prophecies, Luke, and overall godly BS?

  He was dealing with the Roman equivalent, of course.

  First of a five book series detailing all the events of Jason’s time in Camp Jupiter before the events of Lost Hero. Basically what would have happened if Jason got his own series like Percy did. Can be read in counterpart to PJO.
