I should really reread both the books. I loved them as a kid but have almost entirely forgotten them.

I have still never come around to loving The Last Enchantment, but The Crystal Cave holds up as of this summer and I liked The Hollow Hills better this time around. (Besides the relationship of Merlin and Arthur, the sword of Macsen Wledig and the very clever reworking of the fisher king are the points in its favor for me.)
