Let me just start out by saying this is my new favorite book and it is a perfect summer read. I loved sitting on the porch during warm weather days and reading this. I think Morgan Matson is becoming one of my favorite authors. In the book Emily, the main character, has a best friend, Sloane, who suddenly disappears at the beginning of the summer. After Sloane leaves she sends Emily a list of tasks to do by the end of the summer. The whole book is about Emily completing these tasks and while doing this she meets new people and steps out of her comfort zone.
