Susan Choi’s latest novel begins at a competitive, quirky performing arts high school in a 1980s American suburb where two freshmen are falling in love. Jump a bunch of years ahead to adulthood, and Choi’s sharp writing starts messing with your mind: What really happened to the students at the Citywide Academy for the Performing Arts (and what didn’t), what’s truth (and what’s not), is up for debate through the last scene.
