The Azeman, Paperback

Four people with seemingly nothing in common meet in the Amazon jungle. Chosen to help set up a safe haven for the Indians and to train an elite group of elders to venture out as missionaries to spread the Word of God, Dan Marsden and Elaine Hollis must first overcome the terrors of the Amazon as well as defeat a militia sent to destroy them and enslave the Indians in their care. Together with Chet Dallas and Father John, they manage to defeat the soldiers led by Felipe' Mendoloza but the real danger is yet to come. A vampire-like creature, known only as the Azeman, arrives and threatens to destroy all that they've accomplished. To survive, they have to find a way to kill a creature that can't die
