The Girl with the Wrong Name by Barnabas Miller
My rating: 4 of 5 stars
Theo's life changed forever towards the end of her junior year of high school, when something happened in her room late one night. Since then she's been hiding from friends, rarely going out unless it's to film others (using a button cam). One day she meets Andy, a young man obsessed with a woman he met in a "Before Sunrise" type encounter. Her desire to help him find her leads to all sorts of revelations about her life and her family, and the truth what happened That Night. Sadly, the denouement doesn't live up to the rest of the book, otherwise this would have been a solid five stars; as it is, 4.5.
