SOLVED. A book about Noah's ark, fiction, a bit humorous, published before 2013. Early in the book one of Noah's sons comes back with his "exotic" wife (from a few villages away). A lot of it is from the wives' POV. [s]

All the sons help Noah gathering the animals; the youngest often makes fun of his dad's habits.

It's definitely not Not Wanted On The Voyage.

A mild spoiler from the end:

(view spoiler)[I particularly remember at the end, when all the sons and their wives are heading out in different directions to make their new homes, the one wife is talking to her husband and says something to the effect of "Oh my goodness, are you actually happy we got sent in the rougher direction?" (hide spoiler)]

Thank you! I never realized just how many books there were based on Noah's ark until I tried finding this one again.
