Finished the re-read (more a first read - it is a very long time since I read Persuasion) and thought I'd make a couple of observations before I read the book's introduction and find out what I should be thinking.
Trains - after a comment by someone, I now read all 19th century novels with an eye to transport.
There are no trains - but an awful lot of talk of carriages - what a 'small' world these people live in. This transport limitation, when added to the fine distinctions of social class, makes for a most claustrophobic atmosphere - in fact it forces several of the characters to move (and marry) in circles they would otherwise not do. (Inbreeding and associated decline in genetic stock, or what?)
In the 'country' - imagine being confined to a small group of equal status, with a carriage ride, on country roads, in winter. No wonder the attractions of Bath beckon - even out of season (or especially out of season). If you have to stay in one place because of a declining fortune, which place would you stay?
And carriages seem to indicate status as much as modern sports cars - mines bigger than yours and look at the horse power! No wonder then that Mary measures her sister's success in terms of seniority regained AND a better carriage!
The second point that struck was that this is a sequel - without a pre-quel. It's - 'What happens to the old maids, left on the shelf by an earlier disappointment?'
Anne is a woman - not a girl (although treated as such because of her unmarried status).
This is not a novel of adolescent to adult: This is mature consummation.
Anne is no Jane Eyre.
Which brings in another aspect - the world is changing in this novel - all these sailors - lower-class upstarts - new money, new ideas, direct and willing to break down, just a little, social distinctions. (They even move around vast distances - unnatural or what?)
By the time Jane Eyre comes along, this revolution has spread to 'women' too! I suspect Jane would have remained a governess, if Anne had not had her little fling.
