The Once and Future King (The Once and Future King, #1-4)

One explanation of Guenever, for what it is worth, is that she was what they used to call a “real” person. She was not the kind who can be fitted away safely under some label or other, as “loyal” or “disloyal” or “self-sacrificing” or “jealous.” Sometimes she was loyal and sometimes she was disloyal. She behaved like herself.
