The idea of this book was so much better than the execution. I really enjoyed when the book split into dual POV and thought that was some of the stronger parts but when it was multi-pov at once it was confusing and all over the place. I did like the friendship and character development. At first I was annoyed with the girls and the choices they were making and how they were treating each other but it all came full circle and wrapped up nicely in the end. 
However, the ending was HIGHLY unrealistic.

Why the fuck was Josie driving with one foot and one hand?!? SERIOUSLY!! I understand it was a sign of character growth and she finally felt confident enough to drive but like maybe after you're not bleeding out and in shock. Especially when your friend is barely injured.
