My attention wanders in the later books, when it gets into the Arthurian love-triangle stuff -- my patience for love triangles of betrayal and doomed passion tends to be limited, which is why my fascination with Arthurian tales waxes and wanes -- but, oh, I have loved The Crystal Cave for years upon years.

I love the sword of Macsen Wledig in The Hollow Hills and Niniane in The Last Enchantment; the rest stiffens the closer it gets to familiar Arthuriana. But yes to loving The Crystal Cave.
