Mia is the protagonist of the story, a 17 year old girl with brownish hair and blue eyes. She is kind, loving, and devoted to her boyfriend Adam, her family, and her Cello. She gets in a car accident and witnesses her body being taken to the hospital. She has the choice to either die with her family, or stay with Kim, Adam, and her Grandparents, and she chooses the latter.
Adam is Mia's punk-rock boyfriend. He is cool and hipster, and loves to play his guitar in his band called Shooting Star. He has brown hair and brown eyes. He goes to visit Mia in the hospital and goes to see all of her cello concerts.
Kim is Mia's best friend. She is Jewish and has olive skin, and black frizzy hair that she always keeps in a neat braid. She is eccentric and stubborn, and loves photography. She becomes best friends with Mia in their freshman year, and goes to visit her with her mom in the hospital.
