Every time I read something by Katie McGarry, I just want to gush all over it, and Crossing the Line is no exception. This novella was so sweet and yet touches upon all the confusion and uncertainty that comes between high school and college. Katie McGarry captures all that in this lovely little story. 
 Lila and Lincoln are brought together via a shared tragedy. They instantly connect and over the course of the next two years, they get to know each other via letter writing. This might have been a bit of a throw-back in the day of email and instant messaging, but I love the image of Lila with all of her letters strewn across her bed as she struggles with what is happening in her life. Everything is changing around her and she's looking for something to hold on to. She thought that was Lincoln, and now she isn't so sure. 
 I loved these two falling for each other via their letters. The story captured how they built trust and their relationship through their letter writing. When that trust is broken, Lincoln cares enough for Lila to drive the ten hours to see her to explain. 
 I would have loved this to have been longer, but even so, I got to the end with the feeling that no matter what happened between these two, Lila was going to conquer her fears and be able to move into adulthood on her own. Really loved getting a little glimpse of Echo and Noah in this as well, and also hearing how their relationship changed Lila's life. 
 So overall, really terrific novella that captures a very unsettled time in a young person's life. It's a wonderful amuse-bouche for the upcoming release, Dare You To. I can't say enough about Katie McGarry and this series. Love it!
