Earthbound (Earthbound Series, Book 1)

Eighteen-year-old Tavia is the only survivor of a plane crash that killed her parents. Grieving and lonely, she starts having strange visions; of a boy she's never met but feels compulsively drawn to. A boy who tells her to do things she never dreamed of. Tavia begins to suspect that secrets are being kept from her, and that her kindly aunt and uncle know more than they are letting on. Was the plane crash really an accident? Or is Tavia part of something bigger than she ever imagined?
