Although I had never heard of Outlander, somehow my wife, who reads a lot less fantasy than I, had heard of it, through friends and acquaintances who had read the books and had been just as evangelical about them as I have been about A Song of Ice and Fire. How did I not take notice of a popular fantasy series? Unfortunately, I think I know the answer.
Outlander is on Starz (yes, Starz) and the showrunner is Ronald D Moore (Battlestar Galactica). What else do you need to know?
