I was a little doubtful when I got my copy of the book, but i gave it a chance during my many, many, many hours of breastfeeding. (Awesome opportunity to read, BTW.) I ended up liking it quite a bit. It is a pretty good summer read if you're looking for a mindless chick-lit type book. Think something along the lines of a Jennifer Weiner book or The Devil Wears Prada and you've got a pretty good idea of what you're in store for.
Here's the review I wrote for Goodreads.
