I knew who the Dionne quintuplets were—I think my mother must have heard about them on the radio (she was only a few years older) and she told me about them when I was a girl—just that they existed, however. Not about all the hullabaloo.
At the beginning I got sidetracked about the nasty egg that decided it was too good to produce a singleton and decide to split into 5 (or 6, maybe, judging by Wikipedia, which I don’t trust). But I slowly grew to love Emma (never fell in love with the babies/girls, but felt horribly sorry for them by the end). Also loved the descriptions of the surroundings (naturewise). Felt sorry for the mother, too, popping out one kid after another. Sort of shocking to read about life in rural areas in the ‘30s in such detail. Common then in the US too, but I never really thought about it. Anyway, I got caught up in all of it. Totally recommend.
