I read that book too, and I think a polyamorus relationship was vaguely hinted at, even in other accounts of the story.
This is the way I would have written it. Guinevere loves both men and King Aurthur is actually gay and loves Sir Lancelot more than the woman, who is really just a good friend. He is more of a father figure to her. Lancelot develops a deep love for both the King and Guinevere. This triangle is complicated and dramatic because there is jealousy involved and secrecy.
For a happy ending Lancelot impregnates Guinevere and they pretend the son is the offspring of the King. He inherits the crown and becomes a flaming gay King in tights and redecorates the palace.
