Zapped back in time to the medieval court of King Arthur, Callie and her friend invoke the legend of the Lady of Shalott ... with terrifying consequences. Callie and El are twins who live with their father. Callie, the artistic one in the family, loves the story of King Arthur and the Knights of the Round Table. And she loves computers. She wonders what would happen if she could use her father's sophisticated virtual reality program to change history, to manipulate past events? Callie's intrigue and passion lead her to accidentally zap herself and four other teenagers back in time to Arthur's court at Camelot. Not all of them know one another, but each of them have come to a turning point in their own lives in the 'real' world. Each of them must face a personal challenge that will change them forever. And yet danger also unites them as they work through their differences in a desperate bid to find their way back home. In writing Shalott, Felicity Pulman has not only created a compelling story, she has also provided a possible answer to the puzzle of the Lady of Shalott, one of the most intriguing and evocative of the Arthurian tales.
