When Maddy called at 2:30 in the morning, crying and begging for a ride home from a party, Ella grumbles but of course goes to pick up her twin sister. The two argue in the car, hurling accusations of selfishness and general hurtful words at each other. Ella loses control of the car on the wet road, and the car slams into a tree. One sister wakes up in the hospital, unsure of what happened, but everyone is celebrating Maddy's survival. Seeing their joy, Ella doesn't want to tell them that she's the one who survived, not when it was her fault. The least she can do is live Maddy;s life for her. 
 Even more than the attempt to be someone else, this is a well-told, tear-jerking grief story. The parents are grieving the daughter they lost and trying to help the daughter they still have; friends are trying to still be friends while Ella-as-Maddy is acting strange; Ella herself is trying to reconcile the life she was going to have--her own--with replacing her sister's life instead. 
 Hand to fans of If I Stay, and maybe those who were curious about the living-a-twin's-life aspects of The Lying Game.
