I have been approached via my blog by quite a few literary agents but did not like the direction any of them wanted me to take, so declined to properly engage with them.
Personally, I think this has all been done to death, and have yet to read anything in print that really resonated with me. I also can’t help but feel that anyone interested in publishing a firsthand experience will have a very definite idea of the kind of voice/direction they want (which is my experience).
To my mind, the obvious agent to start with is the one who worked with Belle de Jour/Brook Magnanti, and also look to see who represents Rachel Moran. However that said, self-publishing on Kindle or even starting a Patreon or Substack is worth considering too as this will give you complete control in a way working with an agent/editor will not.
