Left Behind by Vi Keeland and Dylan Scott is a tale of loss, family, secrets and re-connections. It is a beautiful story that slowly weaves together the lives of two different people, slowly showing the deeper connections they have that they weren't even aware of. 
 I was so engrossed in this story I barely even noticed it was about high school aged students. The back and forth between Nikki and Zack's perspectives gradually paint a clear picture of who is connected and how. 
 It's so important to not have any spoilers going in I'm really not sure what to say other than it was a fantastic read. I couldn't put the book down, and I was simultaneously desperate to read more while not wanting it to end.
