The Mockingbirds by Daisy Whitney
Alex attends Themis Academy, a boarding school where the staff believes everyone to be perfect and does not engage in dealing with disputes among students. After Alex is date raped, she enlists the help of a group at the school called The Mockingbirds, named after the book
To Kill a Mockingbird. With their help she attempts to seek justice for what happened to her.
This is a good young adult book that deals with a serious issue in a realistic way, as the author herself was date raped in college.
