I LOVE the Outlander series. Had to re-read all the first 7 books as I received #8 for my birthday in July. Right now I am reading the Jack Reacher series by Lee Child. I have read all The Cat Who books at least 4 times start to finish. Love the James Rollins books. Also liked "The Oldest Living Confederate Widow Tells All" (it became a made-for-tv movie in 1994).
I am also a Clive Cussler fan. I've read every book of his that I could find.
