So, I think all of Jen's books (like her blog) are hysterical. Additionally, we have far more in common than I would have suspected given our different life positions and political stances.
That said, Bitter is the New Black is still my favorite. The wit was so biting. It was awesome. This one felt like a lot of the dialogue was manufactured, "So did you know that, Fletch, that XX vintage wine was originally" blah, blah, blah.
The parallels with My Fair Lady were interesting and some of the situations were truly hysterical. So worth the time and amusing.
