Other Arthurian novelists

 Since the 20th century there have been masses of novels about Arthur many by American writers.

Some are good others not so good.  Bernard Cornwell - creator of Sharpe - wrote a trilogy some years ago, which concentrated on Arthur as a ruler and military leader, as might be expected from his work on Sharpe and the Napoleonic wars.  It didn't stick too closely to the legend and I was not a big fan..  Often male writers who tend to portray Arthur as warrior are less than sympathetic to Guenevere, seeing her as a faithless scheming whore.. and in my opinion that isn't a fair portrayal of the character as she has come down through the ages.  Malory says of her that she was a "true lover" and she is generally seen in the older versions of the stories as faulty but lovable. 

Victor Canning, another adventure novelist has also written a trilogy about Arthur as warrior.

Mary Stewart, a romantic adventure novelist, who wrote many works set in foreign countries, also wrote a 4 novel saga many years ago.  Although I've read them, I cant remember much about them, but they stick closely to the legend. 

Women novelists who focus more on the women of the saga tend to bring in fantasy elements, on magic, pagan religion and other worldly experiences, while the warrior centred narratives are usually an attempt at a historically accurate portrayal of the Dark Ages in Britain and on life in the warrior bands.

Gillian Bradshaw's trilogy is partly realistic but also brings in the fantasy elements and religion.  The three books are narrated by different characters; the first one is written by Gwalchmai, (Gawain) Arthur's nephew, the second by Rhys a farmers son who becomes Gwalchmai's servant and the final one by Gwynhwyfar, or Guenevere who narrates about her affair with Bedwyr and the fall of Camlann... and Arthurs death in battle.  The three different narrators make for a balance between the male and female points of view and between historical novel and fantasy novel.  Bradshaw sees Arthur as a Christian  but one who is not popular with the Church because he taxes the monasteries to pay for his wars, and is tolerant of other beliefs.  Morgawse, Arthur's  half sister who seduced him, is the villain, who has dedicated herself to an evil path, but Gwynhwyfar is a woman character who is much more sympathetic.  Gwynhwyfar becomes a nun after Arthur's death and Medrauts (Mordred) and she ends up as an Abbess, following the legendary story.
