Jane Green has written much better books than "The Other Woman," but I would still recommend it for a fun, fast, mindless read; maybe while you are holed up for a weekend with a head cold.
It has a strangely stilted tone that doesn't appear in Green's other books, almost as if she were telling the story from far, far away, through a telephone. I can't explain it more than that, but it has a curious lack of affect to it, maybe because the plot was not close to the author's heart?
At any rate, this book tells the story of Dan and Ellie, a couple who meet, fall in love, get pregnant and marry (in that order), falling into an idyllic life that is marred by only one thing: "the other woman"--in this case, Dan's overbearing, in-your-face, no-boundaries-whatsoever mother, Linda. This woman is so over-the-top awful that she reads as a caricature; you really can't believe her antics or the rather lame reasons that Ellie, a high-powered career woman, folds into helpless girlhood in Linda's presence.
The book meanders on, pleasantly enough, until a denoument is reached. I didn't believe any of it, but I cannot say I didn't like the book. It has Green's usual fun cast of characters (although not half as endearing as in most of her books) and moves along quickly. Just don't expect a "Babyville"--or you will be very disappointed.
