This 1939 book is for highly motivated, very bright fantasy fans who have read everything else in your library and really, really want some heavy-duty Arthurian legend. The vocabulary in this lead me to read it with a dictionary by my side, and the concepts of friendship, world peace, and doing good in the world are handled very philosophically.
That said, I enjoyed this. It has moments of humor, was beautifully written, and laid out the main story of Arthur and the knights of the Round Table in a fairly easy-to-follow fashion. The one thing that I enjoyed, but which gives me pause when recommending it to students, was the Arthur-Guinevere-Lancelot love triangle. The levels of stupidity on all sides was fascinating, and since the circumstances often devolved into chaos and violence, I think that it would keep the interest of those reading this for the action and adventure, but I doubt that students would have quite the interest in the soap opera quality of this sub plot that I did.
I'm glad I got a copy. It's something that will challenge readers that I can hand to them more happily than, say, The Three Musketeers or Vanity Fair (which I finally deaccessioned because if I couldn't finish it after 20 years of trying, what are the odds that one of my students could?).
