A great secret from antiquity is threatened; its eradication, if successful, will lead to mankind’s destruction. There can be no compromise in safeguarding it, whatever the fateful consequences to those entrusted with its continuation. Paul faces impossible choices, ones he cannot make alone. Who can he trust? How can he protect this secret as the world around him falls apart as Outremer descends into a deliberately orchestrated war of unparalleled violence, with Christianity and Islam pitted against one another? Amid the horrors of total war, Paul must decipher the secret, how it has been updated and encoded within the mysteries of Mary Magdalene and the sacred feminine, and how it must be restored if is to be preserved successfully so that mankind can claim its true inheritance, one of unimaginable power. Evil forces wish to control and destroy the secret to stop a new dawn of spiritual awakening, cultivating instead a climate of fear, anger, judgment and the eventual enslavement of our souls. Wiser, braver and nobler individuals step forwards, just as they have always done in the past to intercede against evil, and it is to those men and women Paul must turn. Just when all appears lost, Paul must find true courage, perseverance and faith, and make the ultimate sacrifice. Failure on his part will risk losing this arcane message forever. The time to act is now. Outremer IV is the final instalment of D. N. Carter's epic historical quartet.
