I'm about halfway thru the Outlander book #1, so today I went on a hunt for the rest of the series. Because I can see that stopping after the first is not going to be an option. Turns out the B & N in Brooklyn Park is closed, so I hit the Half price books in crystal, which only had book #5. They gave me the # to the St Louis park store, which had book #2. I drove out there, which by the way is a big "yay me" because I never just get on the highway and drive to a place I don't know how to get to, and they had the book with minimal spine damage that they gave me for FREE!
So if you have books 3 or 4, let me know, I would love to borrow them. And don't try to explain the book to your husband. You just sound dumb.
