If you're interested in medieval historical novels, you might like to try Judith Merkle Riley. She has one trilogy: A Vision of Light/In Pursuit of the Green Lion/The Water Witch, set mostly in England. She also wote two stand-alone novels, The Oracle Glass, set in France during the Affair of the Poisons, about a young woman who may or may not have psychic powers; and The Serpent Garden, set in the England of Henry VIII, about a woman painter. All are well-written and historically accurate as far as I was able to tell, with action and suspense and minimal romance, although the mass-market paperback of A Vision of Light is packaged somewhat like a historical romance. I recently learned that Ms. Riley had died, which makes me sad, as I was hoping to read more books from her.
