The book blurb from some famous author (although I admittedly never heard of him), describes this as "a wonderfully written, funny debut". I am not sure he read the book or maybe he has a different sense of humor, because I did not find it funny. But I did find it well written with a strong heroine and an excellent msytery plot.
You can definitely tell that this book is the first novel published by the author. The writing has too much of the author in it - she's obviously not able to keep her direct voice out of her fiction, which is the mark of a truly great writer (think Shakespeare and Austen).
I picked it up because I read her essay "Good Enough" in "Mommy Wars," which was very good, but non-fiction is definitely her forte. Hopefully, she'll stay away from novels in the future.
Jennifer Weiner handles VERY similar subject matter much better in "Goodnight Nobody," so I would recommend reading that instead.
