It's been a year--a year of missing Nina. A year of milestones--holidays, birthdays, everything without her. Leo feels like she should remember what happened that night. But all she knows is that she left the party and got into a car with Nina and Nina's boyfriend, East. East, who once promised Nina he'd watch out for her younger sister. East, who has been trying to keep that promise every day since. But East won't give Leo the one thing she wants--the one thing she needs. He won't tell her anything about the accident. He won't talk about that night at all. As the days tumble one into the next, Leo's story comes together while her world falls apart. The only constant is the one person who can help her bear the enormous weight of her love for Nina--and East might be carrying too heavy a load of his own.
