Gail Forman's novel is based on the true story of Susie Gonzalez, a girl whose life ended tragically and suddenly.

When Meg, Cody's best friend, decides to commit suicide, the life of a small town changes. Everyone is looking for the reason for her action - loving parents, friends and little brother. He can’t come to terms with the loss of Cody either. They had been together since childhood - how could she not notice that Meg needed help? To understand what happened, Cody goes to the university town where Meg lived until recently. There, Cody realizes that she didn’t know everything about her friend. She knew nothing about her new friends, about Ben, the young man with a guitar and a mocking smile, and, most importantly, about the encrypted file that Meg carefully hid...
