The Stranger — Caroline B. Cooney

From the first moment she sees him in class, Nicoletta is drawn to Jethro, fascinated by his dark, mysterious face. She is attracted yet repelled, interested but afraid. Nicoletta becomes obsessed, unable to think of any-thing but this strange boy.

But she knows so little about him.

Until she follows him to a deserted cave on the edge of town... and learns the truth.

Jethro is not like the others. No, not at all.

He has a terrifying secret. A secret no one must ever find out.
