The International Guild - Douglas Graham - Bog

The Guild is the result of the world going into the dark ages and a group of scientists, theologians, and philosophers that formed a secret society to preserve knowledge. Through the years the Guild became far more advanced than the rest of the world. The First Caste is the adversary of the The Guild. War is imminent between the two.
The book is set in contemporary times. The main character is Michael, and a very special and unique woman named Jane. The longer Michael spends time with Jane the more he realizes there is something very different about her and her family. He learns that she is part of a secret society, a society that he will join. As Michael and Jane's relationship grows a war breaks out between the two groups. Michael and Jane both get caught up in the war.
The book portrays The Guild, the protagonists, as Christians. The contrast is between the Christians and those with humanist world views, The First Caste.
