A lot depends on how well the book is written. Most of my life I was a romance fan, but not the gooy, silly female ones.

When my marriage was breaking up I recovered murder mysteries. My favorite author was Connley. I read some Sandelforth but his books seemed to repeat themselves.

Now I am a huge fan of books about women during WWII in Europe. I look for ones based on real events. I have read some excellent one and some really stupid ones. I won't bother with the authors of the stupid ones again.

Those books all have women doing unusual, for them, and important things. These women were doing men's work while the men were away fighting and dying.

Two of my favorite are The Rose Code and The Girl With No Name.

Very different books Rose Code is about the female codebreakers and the The Girl With No Names is about a young German Jewish girls who is put on the Kindertransport and her life in England after that. both are good for different reasons

Though none of them fall under the category of horror unless you consider what Hitler was doing horror.
