When Stacey hands Aria an invitation to the most exclusive event of the year -The After-Party - on New Year's Eve, she almost says no.

She expects a night filled with overpriced drinks, sweaty strangers, and people doing whatever it takes to chase a high. She's not wrong. But The After-Party is different.

There was something more. Something hidden beneath the music, the flashing lights, the carefree laughter. Something no one can explain.

Because when the night is over, no one remembers what happened.

They only remember the feeling of a high.

And Aria is about to find what the fuss is all about.
