If I stay 1-100

In the first 100 pages of If I Stay there is a snow day for everyone in Mia's family. To bad that its not a good thing. The whole family goes out for a drive. While driving, the end up getting in a car wreck. The scary thing is, Mia can see everything that's going on. She thinks shes still alive, until she sees her hand sticking out from underneath the car. Her body gets taken to the hospital because she is still alive. She is trying to figure out what is going on when her family gets there and wonders how she can move while she is not even in her own body. She gets even more freaked out when one of her nurses says "Shes running the show" What does that mean? How will she find out?
