Immortal

Immortal by Gillian Shields

Wyldcliffe Abbey School for Young Ladies is elite, expensive, and unwelcoming. When Evie Johnson is torn from her home near the sea to become the newest scholarship student, strict teachers, snobbish students, and the oppressive atmosphere of Wyldcliffe leave her drowning in loneliness.

Evie's only lifeline is Sebastian, a mysterious and attractive young man she meets by chance. As Evie's feelings for Sebastian blaze with each secret meeting, she begins to fear that he is hiding something about his past. And she is haunted by glimpses of a strange, ghostly girl—a girl who is so eerily like Evie she could be a sister. Evie is slowly drawn into a tangled web of past and present that she cannot control. As the extraordinary, elemental forces of Wyldcliffe rise up like the mighty sea, Evie is faced with an astounding truth about Sebastian, and her own incredible fate. (source)
