Although this is ostensibly Mordred's book, he is presented through the eyes of a succession of female characters, all of whom come to love him but do not necessarily understand what is going on with him. The young Mordred is pleasurably prickly, if mildly woobified, but towards the end he becomes a withdrawn cipher. Morgan le Fey takes up his slack as the only malicious person at Mordred and Arthur's final battle, while Mordred is seemingly just confused, or even bewitched. Ultimately it seems like both Mordred and his female admirers/narrators get short shrift.
I probably would have eaten this up with a spoon at a younger and less discriminating age, but I find it unsatisfying.
