The seal of Notheos

Notheos, a god erased from all myths, disgraced and sealed away by the Olympians. Someone is trying to free him, so a group of demi gods from camp are off to find him and stop him. Only problem, they don't know where he is. But a six-year-old with her own powers does. I only own half this story, the other half belongs to Kris, Warrior of Death. Give her credit!
