I've asked about these books here before, as I've bought them all (would do so even if I had no intention of reading, tbh) but had huge trouble getting into them.
I watched the first book (first three episodes of season one) adapted for TV as Strike, and now I'm in. I don't know what the hurdle was before, but it gave me the impetus to get into the books and I'm so impressed so far. Obviously I know the ending of Cuckoo's Calling, but am still reading, and there is SO much texture in the books even if you know the twist; and I have Silkworm on Audiobook (library availability) which I'm working through.
Anyway, what struck me is that, beyond being from an author we want to support, and being entertaining reads if one likes mysteries, is that these are thoroughly feminist books. They are perfused with the awareness of how women are treated and shaped by society, on the basis of biology, culture, the law ... it's tremendous, and it is for the most part subtle. It doesn't read (contra some of the reviews) like a feminist, much less a TERF, manifesto; it just reads like a good, entertaining read by someone who incorporates the reality of women's lives into the story and the characters.
Which is good, btw - almost everything I've read that is "ideology based" fiction, for lack of a better word is terrible fiction. (Thinking of some of Robert Heinlein, in particular; I'm a SF junkie, but the politics, and perhaps more precisely their lack of subtlely, make some of the books tedious.)
It's also interesting that she chose to publish not only under a new name but as a man. I think IIRC she was 'outed' pretty fast, but I'd be curious if anybody notices that Galbraith writes women extraordinarily well, for a 'man', before it was widely known that Galbraith was JKR.
Don't think this is a spoiler but being conservative:
Anyway, many thanks to all the Ovarites who answered questions and assured me it was worth getting into it. I can also recommend the TV show thus far; although obviously a lot is cut out when a massive novel is trimmed to ~3h, it seems fairly faithful on the broad strokes, and the acting is fairly good, as well as the production values.
If you're on the fence, I'd say if you like the Kellerman novels, or the latest batch of British mystery hits by women, you'd like Galbraith's books. It's got some grisly bits, but I always find those less disturbing in text than on screen (the books for GoT bothered me far less than the HBO production) and in terms of tone they're way less bleak than the Scandinavian mysteries, etc.
