** spoiler alert ** 
 I really liked the thoughtfulness of this book. The nerve-wracking realities of facing an unknown freshman roommate are well-captured, but I was frustrated by the abrupt ending, which is the reason for four stars instead of five. I know the readers can assume how their actual face-to-face meeting will go based on the last few chapters, but I wanted to SEE it, after watching the two girls be apart the entire book and slowly getting to know each other via email. Other than that unexpected dissatisfaction on the last page, it was an enjoyable read and deals authentically with topics like sex, honesty, friendships, and family life from two different older teen perspectives.
