From the back cover:
They wanted to throw a party...
When Mesa High closed, more than half the students were sent to Tabb High. Among them were Jessica Hart and her best friends, Sara Cantrell, Polly McCoy, and Polly's younger sister--Alice. Together they decided to have a "get to know each other" party. They invited dozens of people: Michael Olson--shy as he was brilliant; Nick Grutler--powerful and insecure; Bill Skater--the handsome quarterback; Clair Hilrey--the gorgeous cheerleader, and "Bubba"--who all the girls loved and hated.
But some people came that weren't invited.
And the evening ended in horror.
Most figured it was a suicide.
They figured it wrong.
