Lock and Key by Sarah Dessen

Lock and Key by Sarah Dessen is about Ruby, a seventeen year old girl who lives alone with her mother. Ruby is left to fend for herself when her mother unexpectedly leaves and doesn't return. After months of living with no heat, water, and little money, child services places Ruby with her older sister, who Ruby and her mother hadn't heard from since she went off to college ten years prior. Cora is now married and lives in an enormous house. She and her husband take Ruby out of the huge public school she'd been attending and put her in a small private school. Everything changes for Ruby.

I really liked this book. Ruby changes so much from the beginning of the story where she is angry and isolated to the end of the story where she is starting to allow people in to her world. This is the third book I've read by Sarah Dessen, and I've liked them all!
