Rosemunde Pilcher is one of my favorite authors, and the Shell Seekers my favorite of hers. But, like the previous posters said, if you like time-traveling historical fiction tossed with adventure, Gaelic, kilts and true love (naughty at times) you have to try the Outlander series by Diana Gabaldon. I'm only halfway through the books right now though, so don't know how it ends.
