Allison O'Malley's plan is to get a good job and take care of her schizophrenic mother. She has even closed herself off from a relationship with Ethan, who she's been in love with forever. But then her father shows up, telling her about a long forgotten Irish people, the Tuatha de Danaan. And Allison must learn to set aside her plan and work with her father if there is even a small chance it could restore her mother's sanity.
