Getting 5 stars from all my librarian friends -- and for good reason! I just read this in one sitting and both laughed and sobbed out loud. The story of introverted Lennie coming into her own and falling in love while grieving the unexpected death of her older sister Bailey hits that funny/sad combo just as dead on as The absolutely true diary of a part-time Indian. Pair with Love Aubrey or If I Stay or Over the Moon if you really want to get yourself bawling. 
 Now I need to call my sister. The sisters were Bailey and Lennie (aka Becky and Laura), and shared a room, and told stories at night. Even though I'm the older and Lennie was the younger, I identified with her a lot. One of the best (heart-breaking-est) sister books I've ever read. 
 I didn't note favorite quotes because there were just too many. That is saying something!
