"By Your Side" by Kasie West
A main character who is locked in a library over the holiday weekend with the school's local bad boy and no one knows where they are?
This is what a girl's dreams are made of!
Autumn Collins likes to be in control. Control over her future, control over how people perceive her, and control over her unpredictable anxiety attacks. That 's why she loves photography - she can control what pictures are taken and how they are taken. It's why she always caves to her friends' expectations- how do you not like someone who is so agreeable? So Autumn has her life all planned out with few surprises in store.
However, after a night of studying, Autumn accidentally gets locked in a library over a 3 day weekend and she discovers fairly quickly that this in one situation she cannot control. With the doors locked, the computers all password protected, no phone in sight and a major snowstorm settling in, Autumn realizes she is in for a long weekend.
But Autumn is not alone in the library. Dax Miller, the mysterious bad boy who has bounced around the foster care system after his drug addicted mother lost custody, is in the library as well. But he wasn't locked in by accident.
