Gabriella "Gabi" Mallory, a star AP student at Central High School, finds herself trapped on a public toilet for hours as a bomb threat forces the entire school into lockdown. The bomb is later disarmed, but the would‑be bomber remains at large, and suspicion falls on everyone. As the school establishes a confidential crisis hotline, Gabi is invited to participate. Soon, the hotline become the battleground for a tense game of cat and mouse: the bomber leaves threatening notes on campus, contacts the hotline with chilling calls, and begins targeting Gabi directly. With her father a lead police detective on the case and her new friends and boyfriend all possible suspects, Gabi is torn between trust and danger. The story follows her desperate race to discern who the bomber really is and whether she can intervene in time to prevent a tragedy.
