Query: Not my Favorite Jennifer Weiner Book

I was a huge fan of Jennifer Weiner, but recently, I'm not in love with her books. This one was no exception. The character development was lacking for the two daughters. The only character that was followed in depth was Sylvia (and she was the most boring of the three of them). I think too much was going on in the story and not enough was explained deeply enough. I think fewer, more concentrated story lines would have been better for this book.
