I know those books; I am friends with the author. I am myself an author of Scottish historical fiction (www.pirateangel.com). The books are good, I enjoy them, and they are better written than the Outlander series. Also, they focus more on plot and character development as opposed to tartan-veiled porn (which I believe Outlander is- I don't think putting a sex scene on every other page qualifies anyone to be a good author, as anyone could do that and sell millions). Lee's history is very good as well, she studied it quite a bit. Anyway, I think you will enjoy the books. The final installment of the series just came out last month, so they are relatively new.
