When Autumn's best friend Connor commits suicide, her normal life falls into pieces. Immediately she feels guilty and responsible for his death, saying she should've noticed the warning signs. The worst part? She was going to finally admit to him that she loved him. But Autumn won't accept that he's gone; she continues to send him e-mails every other day, just like they always used to. At first, she feels pathetic, knowing that she won't get a reply. But what happens when someone who signs only "C" sends an e-mail back?
