School's back in session at John Paul 2 High, and for students J.P. and Liz, not much could be worse.
The little start-up school where both their moms teach has doubled its number of students, bringing in a gaggle of clueless freshmen, singing charismatics, and annoying personages. For Liz, the major annoyance is Mary Summers, her old rival for Brian's affection. For J.P., it's a Byzantine Catholic named Athanasius Courchraine who somehow manages to be even cooler than J.P.
With Celia pushing the gag-inducing idea of creating a Catholic "community" in the midst of formal education, both kids escape to a place where religion is off the table-- Sparrow Hills High.
Then, as Liz joins the cheer team and J.P. becomes the school mascot, they start hearing rumors about the school shooting that happened at Sparrow Hills last spring. The police say the shooter is dead... but is he?
Unable to resist a challenge, Liz and J.P. get on the case. But the more they investigate the hazier the police evidence seems. And if the Sparrow Hills Shooter is still out there, no one is safe...
