Soundless Gale

Amarilla and Eileen Chronis are troublesome twin sisters at 13 years of age who have gotten kicked out of every school they've attended. Yet they're not normal twins. They're demigods -- one of their parents is a Greek or Roman god or goddess. In their case it's their father, who was said to have gone missing after a plane crash. They must now adapt to a new life at Demigod Grounds where they learn how to survive outside the hands of safety. Sounds easy right? Easy isn't in a demigod's dictionary.
