The Reader from Athens said it very well, and I agree completely with every part of her review. I was barely worried about turning 30 until I read this book. Let that be a word of warning to potential readers - now it's as if all these other people's fears of turning 30 have been implanted in my brain. And the author's reassurances fell flat with me - too many were based on just some chatty conversations with the author's many "girlfriends". I think there's some helpful information in the book, and it's often interesting to hear about other people's experiences - but I didn't like the author's implication that we're all "chicks" hoping to get "preggers" before the dreadful age of 30.
