The Last Enchantment (Arthurian Saga, #3) by Mary Stewart. The Last Enchantment was one of those fantasy novels that made me want to really take my time, just to savor the story itself, relishing not only in the classic Arthurian mythos that I love but also in the writing style of Mary Stewart. Beginning with Arthur just having been proclaimed King after Uther's death, and watch him, through Merlin's eyes as he grows into his role. All of the pageantry of the Arthurian legends unfold here.
The whole Crystal Cave series by Mary Stewart (and if you like romance... just anything by Mary Stewart).
