Lock and Key by Sarah Dessen

Ruby, where is your mother?" Ruby knows that the game is up. For the past few months, she's been on her own in the yellow house, managing somehow, knowing that her mother will probably never return. That's how she comes to live with Cora, the sister she hasn't seen in ten years, and Cora's husband Jamie, whose down-to-earth demeanor makes it hard for Ruby to believe he founded the most popular networking Web site around. A luxurious house, fancy private school, a new wardrobe, the promise of college and a future-it's a dream come true. So why is Ruby such a reluctant Cinderella, wary and defensive? And why is Nate, the genial boy next door with some secrets of his own, unable to accept the help that Ruby is just learning to give? Best-selling author Sarah Dessen explores the heart of a gutsy, complex girl dealing withunforeseen circumstances and learning to trust again.

I love all of Sarah Dessen's novels. They are brilliant, and realistic. This is a must read. You wont be able to put it down. This is as good as Just Listen, One of my favorite novels written by her. Put this on your reading list, if you haven't already! x.
