The New girl code book

Charlie is a 15-year-old girl living in Brooklyn, NY who feels as if she’s living in her best friend’s shadow. She’s a little awkward and a lot uncertain - about her future, friendships, and ahem, lack of kissing experience. But then she discovers an idea for an app, The Fashionist, that goes viral and rockets her to fame, both at her school and in the tech community. But everything is in jeopardy as she deals with a catfish who befriends her and steals her code, rumors at school, and the newfound attention of a crush.
