Wracked with guilt over abandoning Cassie and delusional from the weakness of her disease, Lia thinks she see Cassie's ghost telling her that she has to come over to Cassie's side to be as thin as she wants. Lia drifts further down into anorexia and cuts herself, too. Lia is straining the patience of her family, doesn't feel like anyone understands her, and it seems like the only way she'll ever be happy is if she becomes a "wintergirl'' like Cassie.
