Angst of a 16 yo forced to move to a small town in England when her father goes there on a teaching assignment. It is told in the form of emails to her friend back home. However, it is a little unbelieveable that some of thes emails are the equivalent of full book chapter and she uses no internet shorthand. There are no malls, the school uniform is hideous, she is held her back a year behind her age group peers, her 18 yo sister has much more freedom, and her parents go out of their way to mortify her (such as having a "no sex with our daughter" chat with the guy who is escorting her to a party ... "and by the way that includes oral sex, she's too young for that as well."). She finds herself juggling between 3 guys with varying amounts of appeal, as well as providing relationship advise to her friend back home.
A couple of parts defy reason, such as the school being unaware that she'd never had French before. I went to 3 different schools in 6 years in England and always got tested for placement/competency in French at the new school. And since the parents went and met with the headmaster to set her schedule (including the decision to place her back with 15 yos), how would this not have come up? The "ghost" that keeps pulling out all her underwear in her bedroom is never explained, although that may be intended as a subplot for a sequel. Otherwise, it's just a meaningless plot devise to have it happen multiple times without answer.
