It's summer, the days of no obligations and spending every waking moment with your wild best friend. Emily and Sloane have plans, grand plans to do nothing and love every minute of it. But Sloane disappears--her family is gone, the house empty--and Emily is left with a to-do list that Sloane has sent in the mail. Real mail, not email. 
 Emily is a bit of an anti-social loaner. So some of these things on the list, like kissing strangers and dancing until dawn, are a little jarring. ie, things she would never do. Corrections: Things she may do, if Sloane were there pushing her. So Emily makes it her job that summer to complete the list. And, as a result, makes some new friends along the way. 
 I'll put on my honest hat: Emily annoyed me half the time. She's awkward, she avoids people, and she sulks because her loudmouth friend isn't there to speak for her. And, oh my God, I do all of that. So yeah, for some people skinny-dipping and stealing something isn't big news. But it is when you've played it safe all your life. And while she goes through the list, she begins to change. She sees Sloane for who she is, and learns something about herself, too. 
 The reason I'm only giving this three stars? In chapter two, Emily makes a new friend. A boy. And I spent the entire book wishing she wouldn't develop a crush on him. Well. (Please give me a story where a straight girl can be friends with a straight guy. Please.)
