Broch Tuarach ... the north-facing tower:
Outlander (also known as Cross Stitch), Dragonfly in Amber, Voyager, Drums of Autumn, The Fiery Cross, A Breath Of Snow and Ashes, An Echo in the Bone and Written in My Own Heart's Blood.
These eight novels make up the "Outlander Series". Diana Gabaldon is currently writing the eighth instalment in this amazing series; catch is that it takes up to 2.5 years for one of these amazing novels to be written and published, yes I fear I may go insane waiting for the next novel.
Until then, I can re-read these novels, which I highly recommend as you find something new each time you read them or experience a situation in a new way ... the reading never gets boring or expected.
So now we all wait for the next novel impatiently, because of course An Echo in the Bone left us hanging!!!
