Looking for a book (series/novels)

Hi, I read a book where a woman, I think some kind or reporter or something? came to a ranch to spend time there with a very rich man, but she started to fall for him, thinking she wouldn’t like all other females have done for him. I believe he was called like a womaniser or something. It’s hard to explain, but I believe there were more books/novels like this and I read it like good 5-6 years ago so I don’t remember much of it. If anything rings a bell, please help. Thank you.

Long shot because I read this a long time ago and I don't remember it at all, but maybe Rider of the Hills by Miriam MacGregor?

Hi guys.
I am new here ..
Looking for a book where the heroin is a slave from west africa and she is of mixed race I think. She is young and beautiful and gains notoriety. The h is sold to sort of a harem I think. Can't remember much but she falls in love with a good guy and towards the end of the book they agree to meet up at a country house (maybe) but the hero (or heroine) looses his/her memory and doesnt show up. I dont remember much but the book spans the heroines life from a teenage slave to adulthood.
Its a very old historical novel that has a bluish cover I think.
