Liz Dryden, a seventeen-year-old millennial born in 1998, is assigned a research paper in her criminal psychology class senior year. Her topic is something she is unfamiliar with, the Columbine High School Massacre of 1999. When a girl in her class unlikely pairs up with her, Liz is weirded out to find that this girl seems to be obsessed with the event. Things get even weirder when Liz discovers the more she researches the massacre, the more depressed and withdrawn she becomes, like someone else's thoughts and feelings are overwhelming her own. To her own horror, she finds herself feeling attracted toward the shooters, as the girl said she would. One night, when things reach their worst, she turns to drastic measures locked in her room, and falls asleep, only to wake up in a strange bedroom with Nirvana posters covering the walls, Nine Inch Nails on the radio, and the tv advertising the remake of The Parent Trap. It's 1998, the year she's supposed to be born in, but she's still seventeen, and the boy who greets her downstairs in the kitchen tells her to hurry up and eat or they'll be late for high school...at Columbine. Now she has to decide to use her knowledge of the massacre to prevent it from happening, or leave time alone to avoid altering the future. Looks like the research paper is about to become an eye-witness account.
