Guinevere is 13 years old and a tomboy living with her uncle and aunt since the death of her parents. There is a prophecy that she will grow to be the highest lady in the land but nobody takes it seriously, least of all Guinevere. Her aunt, the Queen, is jealous of the prophecy nonetheless and tries to advance her own daughter and hold Guinevere back.
I love Arthurian legend and usually enjoy anything even remotely related to it, but I just couldn't get into this book. It took me a long time to read it and even longer to be able to post about it.
Young tween girls would probably enjoy it, but the true Arthurian fan won't find anything new or special here.
