This was, in general, a good book. A story of mistrust, of the tests a marriage goes through, blended in issues like infertility, family, betrayal, suspicion...
That said, this was the seventh book I read by Barbara Delinsky, and although I like her work a lot, this book wasn´t great. I was "OK". The three women in this story are quite petty when it comes to the father of Gretchen´s baby, each accusing their husbands... Karen clearly had a reason, and she was the character I liked the least. Amanda was the one I liked best.
I would advise this book to someone who has read "Looking for Peyton Place",or "The Summer I Dared" or "Flirting with Pete". Personaly, I prefer her current books.
"The Woman Next Door" was a good story, and that said, I might read it again. The ending was good.
