Lock and Key

After her mom vanished in a stench of drugs and alcohol, Ruby continued to live in the family house alone. Finally found out, the introspective teenager is sent to the luxurious home of her older sister, Cora, whom she hadn't seen in ten years. Everything there seems unfamiliar, uncomfortable, and supremely weird: her fancy new room; her lavish new wardrobe; the exclusive private school where she never quite fits in. Most mysterious of all is Nate, the friendly boy next door who seems to have a deep secret of his own. Another subtle character-driven teen novel by Sarah Dessen, the author of Just Listen and That Summer.
