Most of us have probably read stories of the great Percy Jackson, who gets betrayed, and joins The Army Of Chaos, but what if it happened to someone else. In this story a different man leads the army, and he is none other than Leo Valdez. In this Leo gets betrayed and offered to lead The Army Of Chaos, after accepting he was brought to a distant place where no one could find him. Several years later Leo was called to return to earth for a very special mission which requires more soldiers than just kids trained at a summer camp. So now Leo Valdez returns to earth. I don't own PJO, HOO, or Leo Valdez, I only own this story. (Written by Jericho)

After Leo drank a strange potion, he's acting weird. He wants to destroy Camp Half-Blood and kill the other campers. That's why some of the other demigods need to find ingredients for the antidote. But the search isn't that easy. Many dangers are waiting for the demigods...
