Outlander Series

The Outlander Series, which is called the CrossStitch Series in the UK market, begins with the story of Clair Randall, an English post-WWII army nurse who is trying to rekindle her war-interrupted marriage when she is pulled through standing stones and finds herself in the middle of a violent skirmish in the Scottish Highlands in 1743. She is rescued by the Scots from the clutches of her husband's ancestor, but only to be held in the castle on the suspicion of spying. That's the first 50 pages of this series which has six books, all 500 pages or more. Luckily, for you the series is complete, so you can start with Outlander (or CrossStitch) and read right through to the end of the story with A Breath of Snow and Ashes. Here's a good link written by a woman whose best friend insisted that she read the books over her objections.
