Oh, yeah, if you weren't into the people, they would super all blur together, one queen after another. Her books *were* pretty darn similar.

Jean Plaidy was also only one of the other's several pseudonyms. I happen to know far too much about her and her work because my mother was a fan, and I had so little access to books growing up that I desperately read all my mother's romance novels, even though that's not my genre *at all*. Wikipedia tells me Plaidy (real name Eleanor Hibbert) produced 200 books under her various pseudonyms in her lifetime, which I think has a lot to do with them being so similar.

And now I am glad I have access to other books. :)
