Exchange (v.): 1. Hailey Brookes trades in her original summer plans to, instead, swap places with a family friend's young son and live at their suburban estate. Having just been dumped by her boyfriend Ben, her goal for the summer is to steer clear of guys - after all, she's in no rush to find a substitute relationship. 2. Matt Dewchester lives, much to Hailey's dismay, one hallway down from her in her new home for the summer. A charming and funny soccer captain, he seems determined to change her mind - and indeed, both find that there is much to give and much to lose in their blossoming relationship.
