Olympus' Lost Daughter

Kilea Waterstone (16) is a first year history student at Harvard. She's yet to decide her major when she goes on a school trip to Greece. The trip is amazing, ofcourse except from the load of Greek mythology surrounding Kilea. But when Kilea decides to sit down at the pool and listen to music, she can't help but sing along. Kilea accidentally kills someone. She finds out more and more about her true nature.
