The Pride of Lions

It's a rich historical fiction set in Scotland in the 18th century. Kinda like Outlander but without time travel. It's well done in terms of world building with lots of historical references regarding the Jacobite rising of 1745. It's an exciting book and the rhythm is good.
There was one thing that caused me uneasiness in this book: the prevalence of a raping theme. I know it's historical and you can argue that that's how things were back then, but it's a fictional romance novel and I expected less of it. For example, even though it's not explicit, the “male hero” (Alexander) clearly uses the implicit idea of rape to frighten the heroine (Catherine). Every men on the road that encounters Catherine (or any women for that matter) thinks about “taking advantage” of her. So maybe the setting was too historical/realistic for me?
