i agree - it's defniitely more about the harsh realities of relationships, getting to grips with being with someone who you can know so well & yet still have them be a stranger, keeping secrets from one another, working out your problems & trying to just keep it all together - if that's not a real relationship, i don't know what is. Niffenegger certainly writes it well. I think it's a contemporary classic that will most certainly stand the test of time & have people talking about it many years from now. It's made of the kind of stuff that endures.
