Since You've Been Gone - Morgan Matson

I received my copy through goodreads first reads. I loved this book. This is the first Morgan Matson book that I have read and I am now a fan. 

Since you've been gone is about Emily's summer after her best friend disappears without warning and the only thing that is left for her is a list of things to do. This is a heart warming story about new friendships, adventure and stepping outside your comfort zone.
