A Scottish tale of deep passion, with the added feature of time travel, Outlander by Diana Gabaldon is a must-read (pro tip: watch the Outlander series on Starz once you're done). The time-travelling fantasy book series revolves around Claire Randall, a World War II nurse from 1945, who magically transports to 1743 Scotland through an ancient boulder. She soon falls in love with Scottish soldier James Fraser, who is a dichotomy between innocence and sex appeal, strength and fragility. Here, you'll find real-life historical references mixed with mysticism.
