Now a Starz series by the same name, "Outlander" by Diana Gabaldon is a time-travelling fantasy series that spans two different time periods and two different lovers. Claire Randall, a World War II nurse from 1945, is transported to 1743 Scotland when touches a boulder in an ancient ruin. As she learns to defend herself in a new land, she also falls in love with Scottish soldier James Fraser, who is adventurous yet innocent, strong yet sweet. Pro tip: watch the series, too. You'll go for the real-life history blended with magic and fantasy, but stay for the spellbinding sensuality.
