As You Walk on byAs You Walk on by

After a disastrous promposal at a party, seventeen-year-old Theo has an existential crisis in an empty bedroom, but as the night progresses, various classmates also seek refuge from the party, and Theo finds he is not as alone as he thinks he is.
Theo Wright's plan (well, more like his dad's plan) involves excelling at his magnet school, getting scouted by college recruiters, and going to Duke on athletic scholarship. After his best friend Jay dares Theo to prompose to his crush at Chloe Campbell's party, Theo's ready to throw caution to the wind and take his chances. The promposal goes epically wrong, and Theo seeks refuge in an empty bedroom while the party rages on downstairs. As the night goes on, Theo finds he's not as alone as he thinks: one by one classmates join him to avoid who they're supposed be outside the bedroom door. -- adapted from jacket
