Five years ago, Andie Bell was murdered in the quiet town of Little Kilton. Everyone knows the story: her boyfriend, Sal Singh, killed her and then took his own life. The case is closed. But Pippa Fitz-Amobi has never quite believed it. When she chooses the murder as the subject of her senior capstone project, she tells herself she is only reopening old questions for a school assignment.
The deeper Pip digs, the less the official version holds together. With the help of Ravi Singh, Sal's younger brother, who has spent years living under the weight of his brother's supposed guilt, she starts tracing the last hours of Andie's life through interviews, old messages, and secrets the town would rather keep buried. Someone notices. As anonymous threats begin to arrive, it becomes clear that the truth is still dangerous, and that the real killer may be much closer than anyone imagined.
Told through Pip's project log, transcripts, and maps alongside the narrative, Holly Jackson's debut is a tightly plotted whodunit that helped define a wave of modern young-adult crime fiction. It is a story about the cost of certainty, the pull of an unsolved case, and how far an ordinary teenager will go to be sure she has found the truth.
