Twins, Roslyn Chapel, descendants of Jesus of Nazareth
Adult mystery about the secret descendants of Jesus of Nazareth. A girl and her grandfather are the main characters. At the end of the book they come to Roslyn Chapel where they go into a hidden underground chamber and where they meet the girl’s grandmother and twin brother, whom she didn’t know existed. It’s not The Da Vinci Code, I must have read it 10-15 years earlier.
Possibly Lewis Perdue’s ‘Daughter of God’? Or one of Elizabeth Cunningham’s ‘Maeve Chronicles’ series?
Ooh, I’ve read that book… I think it’s either “The Expected One” by Kathleen McGowan or “Labyrinth” by Kate Mosse. I read them both around the same time but I think TEO is the book you want.
Never mind – it is not either of those. I was thinking of Da Vinci.
