A few months ago I read a book by Lewis Purdue called "The Daughter of God." A thread in the Off Topic section brought this book back to my memory. Here is a brief synapse of the book:

--"When Zoe Ridgeway, a prominent art broker, visits Switzerland with her husband Seth, she expects to purchase the rich estate of a secretive art collector. But before Zoe can complete the transaction, she and Seth are drawn into a thousand-year-old web of conspiracy, murder and intrigue that begins and ends with the mystery of a female Messiah, a young girl whose existence, if proven, would explode the very foundation of Western culture."

Very good book. Well written and really put together. Plenty of suspense and action. As the title indicates, it is about religion. It is neither in favor of- or against it. It presents new ideas and it has an afterward where Lewis talks about religion. A break-away from my Vampire-themed literature, but definately a keeper. I hope this helps and I hope you read the book
