Losing Faith (Unabridged‪)‬

When Brie's sister, Faith, dies in a fall from a cliff, Brie's world falls apart. As she goes through the bizarre and devastating process of mourning the sister she never understood, Brie must also contend with increasingly distant parents, her boyfriend's betrayal, and her sudden outcast status at school.

And once she's over the initial shock of Faith's death, Brie is encountering more questions than closure: Certain facts about the way Faith died just don't line up. She soon uncovers Faith's role in a dark and twisted religious cult - a cult that now wants Brie as a member.
