A child of a historical Greek mortal has never been born. But now, for the first time in thousands of years, there is one. Bailey is a half-blood daughter of Medusa. No one knows her godly parent, and Bailey is afraid of what will happen to both herself and the other campers. But when her godly parentage is revealed, everything changes.
