Pretty much the entire plot of this book revolves around sex. Oh, and lying to your parents in a major way for an extended period of time. Add a lot of heavy drinking and partying into the mix, and that's this book. 
 The circumstances and the behavior of the adults and teens are just too unbelievable. I felt like I was reading about a wild sorority house in college instead of a bunch of 16-year-olds. (Yeah, I'm supposed to believe these high schoolers fool their parents into letting them live alone without adult supervision and daddy bankrolls it by giving our protag $1000 a month...and when our protag confesses to her mom, her mom doesn't care because she's too petty to talk to her ex-husband???) 
 And I'm sorry, but kids who skip school and get drunk on school nights and don't study do not get full rides into Columbia and NYU. Can we please be a little realistic here? 
 There's a lot more to teens than sex and getting drunk.
