When asked what authors or novels is ‘September Mourning‘ like, I would say:
Dan Brown’s books in that it contains mysteries in ancient archaeology, architecture, eschatology and history. However, I don’t follow DB’s idea that Jesus and Madeleine had a romantic connection or divine heir-ship threads.
C.S. Lewis’ Screwtape Letters in the personification of entities and the modus operandi of such entities to interfere in the lives of human beings.
David Flynn’s books in the connection of sacred numbers and geography, in the strategic infiltration of sacred knowledge to influence the continuing of technological advancements, and how all roads leads to Jerusalem as a sign from God that He keeps His promises.
Marcy and George are reminiscent of Clive Cussler books in the interaction of the married couple solving mysteries together.
