I decided to start grouping together some of the books that I read last year for which I didn't really have a lot of detailed thoughts. I read the above three books and found them to be vastly different in their "take" on the whole Arthur story and also in my enjoyment of them.
Queen of Camelot by Nancy McKenzie. A compelling story told by Guinevere herself in which she comes across as strong, but also full of emotion and love. On the night she was a born an old wisewoman tells her father than Guinevere will be a great lady one day but that she will betray a king and be betrayed herself. When fighting breaks out in her homeland, her father sends her to live with her aunt's family. It is here that she meets Arthur and ultimately marries him, much to the dismay and envy of her cousin Elaine.
When Guinevere realizes that she is unlikely to give Arthur a son, she agrees for his son Mordred to be brought to court where she will raise him. She and Arthur are happy but Mordred turns against them and kills Arthur. My favorite of the Arthur stories that I have read so far. The characters are fully developed and the whole storyline doesn't hinge on Lancelot and Guinevere.

The Mists of Avalon by Marion Zimmer Bradley. Told primarily from the viewpoint of Morgaine who becomes a Priestess of Avalon. As the making of Arthur's life takes shape, his half sister, Morgaine, is sent to live with her Aunt Viviane, The Lady of Avalon. There she learns what is necessary to become a priestess with the goal of one day taking Viviane's place. Part of her initiation involves sleeping with a young man wearing a buck's head while she herself is costumed. Morgaine is horrified to learn that she has slept with her brother (Arthur) and even more horrified when she learns she is pregnant. When the child is born, a son, he is sent to live with Morgaine's sister, Morgause, to be raised with her sons.
Arthur becomes King and marries Gwenhwyfar. In return for Viviane's help in putting him on the throne, Arthur has agreed to allow his people to continue to follow the old earth religion if they want to. Gwen, a Christian, is not happy about this and continually blames Arthur's leniancy in this aspect for her inability to have children. But Arthur remains true to his word. When Viviane's son Lancelot arrives at Arthur's court, he and Gwen are instantly drawn to each other. Arthur would be blind to not see it and being sure that Gwen's inability to conceive is his fault, he suggests that she sleep with Lancelot in their bed and with him the same night so that if she does get pregnant, it could be considered as his and conceived in the king's bed. Although she hesitates at first and is afraid for her soul, her desire for a son eventually causes her to agree.
Eventually Lancelot and Gwen are not able to keep themselves from each other and Mordred sets a trap to catch them. Morgause has managed to poison Mordred against Arthur, Morgaine and Gwen since she wants her own sons to inherit England and she had been manipulating things for years to ensure this happened. Given the chance to run away with Lancelot, Gwen realizes that Arthur will always be between them and she sends him away and goes into a convent. Arthur is killed and Morgaine takes him back to Avalon.
Although I thought parts of it were rather slow and some things were drawn out more than they needed to be, overall I liked this book a lot. I found the information and descriptions regarding the old earth religion very interesting as well as its clash with Christianity.

Guenevere: Queen of the Summer Country by Rosalind Miles. In this version, Guenevere comes from a line of female rulers in the old earthly religion. Her ability to rule over her lands is saved by Arthur agreeing to marry her and uniting their kingdoms. The struggle between the old and the new religions is a central theme. Although this book is the first in a trilogy, I won't be reading the other two -Guenevere is a whiny, selfish child and she annoyed the hell out of me. I wanted to slap her several times. Since she comes from a female dominated society, she is used to having her own way and she thinks all of the men are in love with her. She is intolerant of the Chrisitian religion that is making its way across Europe and into England. Apart from Guenevere's personality, the actual story line is pretty good, but I found her too annoying to enjoy it.
Merlin battles Guenevere for Arthur's loyalty and Arthur's half-sister Morgan seduces him and becomes pregnant with his son, Mordred. Lancelot and Guenevere have an instant attraction but vow not to act on it because of their love for Arthur. I guess if you read the other books in the trilogy you find out if they stay true to their word, but in this case, I won't be finding out.
