Taylor Edwards family might not be that close - everyone is a little too busy and overscheduled, but for the most part, they get along just fine. Then Taylor's dad gets some devastating news, and her parents decide that the family will spend on last summer together at their old lake house in the Pcocono Mountains. Crammed into a place much smaller than they are used to, they begin to get to know each other again, but as the summer progresses they're more aware than ever that they're battling a ticking clock. And as Taylor tries to deal with the drama at home, she is faced with the fact that the friends she thought she'd left behind haven't actually gone anywhere. Her former summer best friend is still living across the lake and still as mad with Taylor as she was five years ago, and her first boyfriend has moved in next door...but he's much cuter at seventeen than he was at twelve.
