Trying to remember the title of a book I read in the late 90s ish.
It was about three couples, linked by the fact that they had young children/babies.
It was about how their relationships became tangled/ broken down.
There was an affair (perhaps one of the men slept with all three women behind their backs?). There were children being left with a nanny at one point and something to do with a postcard from a Greek Islands. I think one of the wives had always wanted ti go.
There may have been a book club link. In fact I think 'club' was in the title.
I'm off for another google, will check back in a bit to see if anyone knows what I am on about!
