Abbi Hope Goldstein is like every other teenager, with a few smallish exceptions: her famous alter ego, Baby Hope, is the subject of internet memes, she has asthma, and sometimes people spontaneously burst into tears when they recognize her. Abbi has lived almost her entire life in the shadow of the terrorist attacks of September 11. On that fateful day, she was captured in what became an iconic photograph: in the picture, Abbi (aka "Baby Hope") wears a birthday crown and grasps a red balloon; just behind her, the South Tower of the World Trade Center is collapsing. Now, fifteen years later, Abbi is desperate for anonymity and decides to spend the summer before her seventeenth birthday incognito as a counselor at Knights Day Camp two towns away. She's psyched for eight weeks in the company of four-year-olds, none of whom have ever heard of Baby Hope.
