Kings War (Knights of Breton Court Series #3)
I think I enjoyed this more than I enjoyed the second book (the first is still my favourite), but I felt a little bit like I got the abridged version. I would have liked more of it, especially the bits with the holy grail. Still, now that I've finished them all, I have a tremendous appreciation for this series as a whole; it's both imaginative and grounded, and I think the legend translates astonishingly well.
