Guinevere's Gift — Nicole St. John

Lydian Wentworth has married a family friend who is twice her age. Lord Charles Ransome is a fascinating, although crippled, scholar and artist whose historical specialty is King Arthur. But as Charles's physical and mental health deteriorates, Lydian finds herself turning more and more to his assistant, Lawrence, for help and support. Gradually she begins to realise that the three are reliving the tragic triangle of the ancient King Arthur's court.
