There is something magical about the Outlander books by Diana Gabaldon. Sure, there is the element of time travel, but that is not the only thing to capture you. There is adventure, anguish, childbirth, history, marriage, romance, war, and whiskey. And more.
The books of Outlander defy a single genre placement. Probably the broadest term you could use would be historical fiction, but that still does not fully capture the presence of a 20th century English woman in 18th century Scotland, as the main protagonist, Claire, is the first person narrator of our tale.
