Taylor Before and After tells the story of Taylor Harper through journal entries alternating between two timelines before and after a drunk driving accident, in which Taylor Harper was a passenger - and her brother was the driver. Before, Taylor was finally becoming popular, navigating the pressures of friends, frenemies, and a cut-throat initiation challenge by the coolest girl in school. After, she finds herself ostracised, bullied, and facing the glaring silence of things unsaid at school and at home.
