There are a couple of flavors I like in Highlander romance -- I enjoy the ones that are straight up historical; but mmm, a Highlander story especially if it involves time travel? Yes! Maybe you have seen the new Outlander television series? Guess what? It's based on a book!
The story starts with Mrs. Claire Randall on her second honeymoon in the Highlands of Scotland. It’s 1945 and she's a former combat nurse who has taken up the hobby of botany to fill her free time. She is gathering plants at the stone circle Craigh na Dun when she is transported through time to 1743, and finds herself in the midst the fighting prior to the Jacobite uprising of 1745.
This first novel of the Outlander series by Diana Gabaldon is a passionate romance with depictions of wartime violence, and steamy sex scenes. If you're squeamish about these things this isn't for you. Presented in the context of the times, these details give the story historical resonance. I found comic relief in Claire’s swearing. She doesn’t swear like a sailor but she swears like a healthy woman dealing with brawny men, exciting, brutal times, and frustration. I don’t know about you, but if I was a fish out of water I might swear a lot too. If romance, brawny men in kilts and time travel are among your favorite flavors too, there's more to explore in my list, Scottish highland romances.
