In the "About the Author" portion of the book, Megan Crane says that she was inspired to write this book after going to see Mean Girls with her boyfriend. Once I read that, the whole book made sense.
I think it is definitely worth writing a book about the ups and downs of friendships, especially between women, but Crane has written a book about the friendships of 30 year old women in the style of a movie written for teenagers (and don't get me wrong - I watched Mean Girls too!). I think there's a difference between the friendships and cattiness of high school cliques and the deep bonds of women who have known each other for a decade in adulthood.
The writing was strained. There were at least five different storylines going on, each of them painfully obvious, and Crane lacks the skill to turn words in the style of many of the better chick-lit authors.
The story - Augusta is a librarian who has two close friends, but has a large group of friends who always invite her to parties (never mind that these friends are nameless - they're just friends who host an engagement party or a Christmas party or something - she never mentions who those friends are!). She had been dating a guy she's known since college - he was the Hot Guy, and she dated him for four months when she caught him cheating on her with another one of their social set (a "that girl" who always has guys falling all over her).
So Gus gets mad at the girl, tries to get the guy back (why??) and has all these self-discoveries about adulthood, but this was another problem of mine with the writing - it was all so obvious! And plots and subplots just kind of appeared and disappeared during the whole book. Near the end we find out all kinds of things about Gus's boss, which is supposed to make us (and Gus) think about her fights with her friends, but it comes off all weird because the boss hasn't said a word for the entire book. Also, it seems like this book was written in stages. Like when Gus was having a heated conversation, she thought it felt like she was having a Tori Amos moment. And then, three pages later, one of her friends yells at another one for constantly living in a Tori Amos song. So I think maybe Little Earthquakes was on in the background as she was writing those pages???
Anyway, there are so many great books out there that cover areas like this - Something Borrowed by Emily Griffin, for example, is a much better choice.
