Ideal that is, until she receives a letter from Adele Lake claiming to be a direct descendant of a child by Guinevere of Camelot and Lancelot du Lac. Flying to Paris to research Adele's claim, Gwen is immediately swept up in a mystery after Adele's aunt is murdered and Adele herself kidnapped. With the help of Adele's brother Val, and excerpts from Tennyson's 'Lady of Shallot,' Gwen has only eight days to discover the secret proof the Lake family claims to possess, and find the mythical sword Excalibur to ensure Adele's safe return. Follow Guinevere Arthur on a modern day quest through ancient ruins and timeless relics to discover the secrets of Camelot.
