The missionary

David Eller and his wife, Christie, work to help rescue impoverished children in Caracas, Venezuela. But for David, that isn't enough. when he's given an opportunity to do something more--to heal the disease rather than working on the symptoms--David decides to go for it. But little by litte, he falls into an unimaginable nightmare of espionage, ending in a desperate, life-or-death gamble to flee the country with his wife and son.--From publisher's description.
