Goddess of Legend, by P.C. Cast (author of the House of Night young adult vampire series), borrows the premise of Twain’s A Connecticut Yankee in King Arthur’s Court in that a modern woman is transported back in time to Camelot. In this book, a young woman is transported back by a spell cast by Viviane (who in this version is Merlyn’s companion). Viviane has brought the modern woman to Camelot right before the woman would have died in her own time.
Viviane’s goal is to prevent Lancelot’s and Guinevere’s affair from ruining Camelot, because Merlyn can see the future and has become so despondent about what will happen to Arthur that he has lost the will to live. Viviane instructs her recruit to win Lancelot’s affections in order to keep Guinevere and Lancelot apart. However, her recruit falls in love with King Arthur instead.
The voice has a young adult chic-lit tone, and many of the jokes relate to conveniences we take for granted (like indoor plumbing). Magic is used frequently.
