The author of the bestselling YA thriller, One of Us is Lying is back with a new high school mystery.

This time, three seniors (one-time best friends who drifted apart after middle school) each need a break and decide to take a clandestine day trip to Boston when they should be in school.

Ivy really doesn’t want to go to the assembly where her opponent for class president will be sworn in. Mateo needs a break after working multiple jobs to support his mom after the family business closed. And Cal just wants to reconnect with his old friends after being stood up by his secret girlfriend.

The trio is struggling to decide what to do on their day off when they spot Boney, Ivy’s political rival. Ivy needs to know why he’s skipping his own inauguration, so they follow him across the street, into a private building, and onto the scene of his murder.

Now Boney’s dead, the kids are the main suspects each with secrets that connect them to the crime, and the killer might be coming for them next. They need to solve this mystery fast before they end up dead, or even worse, grounded.
