Another Nora Roberts fan here.
Ken Follett writes great books that aren't romances (most are adventure with history, romance, and mystery tossed in), but all the ones I've read by him have a strong romantic element involved; Pillars of the Earth is one of his best as far as romance goes, IMO.
And I admit to reading Harlequin Historicals every once in awhile when I want a bit of fluff with absolutely no substance
