And Both Were Young
Madeleine L'Engle1949

Flip feels like a prisoner when she first arrives at boarding school in Switzerland; her days are strictly scheduled and she never has a minute to herself. She's constantly surrounded by girls who never stop talking about clothes and boys, making Flip feel lonely, clumsy, and awkward. Then she finds a true friend in Paul. He understands her in a way no one at school does, and she breaks the rules to spend time with him. But as the two become closer, Flip learns that Paul has a mystery in his past. To help him discover the truth, she must put herself in serious danger.
