This was useful reading for me. As a male reader, it was illuminating to see the world through the female protagonist's eyes. Apparently there are lots of feelings involved, all of which are examined, carefully, slowly, and lovingly. I also appreciated the portrait of life for unmarried people in their late thirties, as the fork in the road between parents and non parents becomes harder and harder to cross over. "Sorry, I couldn't find a sitter; see you in 17 years" really stung.
The plot moves briskly, the characters are compelling, and what I thought was looming as a terrible, horrible, punishingly unfair resolution to the book's central conflict didn't play out like I was afraid it would.
For whom would I recommend it? Men who would like a view into another world? If I recommend it to unmarried, childless, funny, smart, attractive female readers, the book suggests that they might read into it some kind of meta-message. All I'd be saying is that I liked the book, and you might too, but clearly men are kind of obtuse about this sort of thing.
