Mainly for
star_tourmaline and
rosathome though I suspect they already know about it, the Telegraph on Saturday had a piece about writing a Mills and Boon
http://www.telegraph.co.uk/lifestyle/8316633/Guilty-Pleasures-How-to-write-a-Mills-and-Boon.html Personally I tried a couple when I was a teenager and found I'd got to the end whilst still waiting for a plot and characterisation to start but clearly other people's mileage varies.
Am also really not sure how the genre squares with feminism.
