With that question from the social worker, Ruby knows the game is up. She's been living alone in the old yellow house, waiting out the months until she turns eighteen and can finally be on her own legally. It certainly wasn't in her plan to be reunited with Cora, the sister who left ten years before, and brought to live with Cora and her wealthy entrepreneur husband. Suddenly life is transformed: a luxurious house, private school, new clothes, and even the chance of a future Ruby couldn't have dreamed of. So why is she wary, unable to be grateful, incapable of letting anyone close? Her old life has been left behind, but where does she fit in this new life? Only Nate, the genial, popular boy next door, seems to understand, perhaps because he's hiding some secrets of his own. Funny, perceptive, and touching, Lock and Key will delight the legions of Sarah Dessen fans and win many new ones.
