I should have known better than to get a free book, but I figured I'd try it.
I can understand making Gwenyvere a more independent and spunky character to modernize the story, but not at the sacrifice to the story. I cannot recall Gwenyvere's father being lord of Camelot, nor can I remember ever seeing a story where Arthur forces all lords to swear fealty to him.
Honestly, the story was very poorly written. The story never really went anywhere, and there were a number of spelling errors, which were really glaring due to the bad writing.
