Lost

With secrets she's never confided to anyone, Hazel moves away from her hometown the summer before her senior year of high school. At the insistence of a friend, she begins using an app designed to allow anonymous confession to another user of the app. While she hides her secrets in real life, it becomes increasingly easier to share with the person on the other end of her messages, and she creates a life in which she can be open about her past. But her own secrets combined with those of the people around her threaten to destroy both of the lives she's found herself living.
