It depends on what genre you are looking for.
Mystery/medical "Postmortem" by Patricia Cornwell, it's the start of a great series.
Romance/life "Birthright" By Nora Roberts.
Paranormal "Guilty Pleasures" By Laurell K Hamilton
Mystery/Political "The White House Connection" By Jack Higgins
And then there is Slaughter House 5, My DD swears by it.
