The Mockingbirds by Daisy Whitney
From the glossy pages of its admissions brochure, the prestigious Themis Academy appears perfect in every way: exceptional academics, extraordinary students, the kind of extracurriculars to make an Ivy League proud, and zero instances of student misbehavior. But this boarding school isn't as pristine as it appears. There's a dark underbelly to the perfect record the Themis administration flaunts. Student infractions are rampant, and it's up to a secret vigilante society, the Mockingbirds, to maintain order on campus--a responsibility their members take very seriously.
Alex Patrick never thought she would need the Mockingbirds. But when she's date-raped by another student, she doesn't know where else to go. As much as she'd like to forget what happened, she can't escape the daily reminders of what went wrong that terrible night. Before she can summon the courage to take a stand, she'll have to accept that her battle for justice is not hers alone. Standing up for someone, especially yourself, is worth the fight.
Review from School Library Journal:
Alex wakes up in a strange bed, naked, and with a terrible headache, lying next to a boy whose name she doesn't know. A junior at an elite boarding school, she is used to a controlled and nearly perfect life. Among all the talented and special students at Themis Academy, Alex is a standout as a classical musician. How could she have been so stupid as to have sex—for the very first time—with this stranger? It takes several days, and the support of her roommates and friends, for her to piece together the events that led up to that horrible morning. The portrayal of the aftermath of alcohol-fueled sexual assault is particularly well drawn. Alex is confused, disoriented, and deeply shamed, but her friends help her understand that, no matter how drunk she was, sex without consent is rape. There is no help from the school authorities, who have failed to protect students from one another in the past, so Alex turns to the Mockingbirds. This semisecret society is an ingenious student-initiated justice system that holds individuals responsible for their actions. Just like in the world outside, the wheels of justice turn slowly, but ultimately Alex has the satisfaction of holding her assailant to account. Particularly poignant is Alex's growing relationship with a kind and caring boy who helps her regain her equilibrium and look to the future. Written with a deep awareness of post-trauma experience and a keen ear for high school dialogue, this novel makes an impassioned case for youth taking responsibility for the actions of their peers.
