A teacher is dead. Five students share the same alibi. One of them is lying.
When Mr. Callahan is found murdered two days after a senior project dispute, the police accept the clean story: five top students were together all night. Case closed.
Quinn Reeves knows better.
She was the sixth member of the project-until she exposed fabricated sources and was voted out. She warned Callahan. He promised to "look into it."
He was dead forty-eight hours later.
With nothing but archived group chats, doorbell footage, cell tower logic, and a photographer's late-night images, Quinn begins reconstructing the truth. The alibi fractures. The timeline collapses. And one by one, her former teammates' stories stop lining up.
But someone knows she's looking.
A threatening note in her locker. Deleted messages. Gaps in testimony. A digital trail that doesn't disappear as easily as someone thought it would.
Because in a world built on screenshots, cloud backups, and Wi-Fi logs-
the truth leaves a signal.
The Senior Project Alibi is a sharp, fast-paced YA mystery about digital identity, academic pressure, and the cost of silence. Perfect for readers who love twist-driven investigations with smart, relentless protagonists.
