When Alex Patrick was assaulted by another student last year, her elite boarding school wouldn't do anything about it. This year Alex is head of the Mockingbirds, a secret society of students who police and protect the student body. While she desperately wants to live up to the legacy that's been given to her, she's now dealing with a case unlike any the Mockingbirds have seen before.
It isn't rape. It isn't bullying. It isn't hate speech. A far-reaching prescription drug ring has sprung up, and students are using the drugs to cheat. But how do you try a case with no obvious victim? Especially when the facts don't add up, and each new clue drives a wedge between Alex and the people she loves most: her friends, her boyfriend, and her fellow Mockingbirds.
As Alex unravels the layers of deceit within the school, the administration, and even the student body the Mockingbirds protect, her struggle to navigate the murky waters of vigilante justice may reveal more about herself than she ever expected.
