Emma O'Connor is mourning the loss of her best friend Cheyanne Wrangler after a serious car accident. She has done nothing but hide in a depression for a month since her funeral. She is even forced to go to therapy by her mom.

Now to grieve for the loss of her friend, she writes her friend letters in a journal every day about her day and what has happened since her accident.

But she is determined alongside of Cheyanne's sister Leah to figure out who the driver was that killed their best friend and figure out what really happened that night.
