Great question!
Well, I read vociferously, and I read fast. So I tend to like longer books, and serials (because I get super frustrated when it's over too fast). Books that I have read more than once:
Margaret Mitchell: Gone with the Wind - my personal favorite, x4 at least
JK Rowling: Harry Potter - several times, lost track
Charlaine Harris: Sookie Stackhouse series - x4 at least
Janet Evanovich: Stephanie Plum series - x3 at least
Stephen King: Talisman and Black House - x3 or so
Diana Gabaldon: Outlander series (generally the first four books)- also x3 or so
Katie MacAlister: the Aisling Gray dragon series - x4 or more
Karen Marie Moning: the Fever series - x 2
Patricia Cromwell: Kay Scarpetti series - x3
Jeanine Frost: Cat and Bones series - x3
Tom Clancy: Jack Ryan series - x2
WEB Griffin: The Corps series - x2
Anything by Jennifer Crusie - at least three times
