If I Stay by Gayle Forman was such an incredible book. I actually read it in one night, and then downloaded the sequel, Where She Went, and read it the next morning.
In If I Stay, Gayle Forman tells the story of Mia, a talented cellist teenager who is in a horrific car accident that leaves her an orphan left in a coma. The entire story is told with Mia's soul (I guess?) floating around and seeing everyone she loves try to encourage her to either stay alive or join her family.
I really loved this book and the characters Gayle Forman created. I felt like I was interacting with them as I read the story. This is definitely something you'll start reading and be unable to put down.
Oh, and the movie adaptation of the first book comes out August 22nd. I'm probably going to go see it and bawl my eyes out. I totally cried while I was reading this book.
