The Mayan Glyph

An excellent read! Get your bug repellent and hiking boots ready for a trek through the jungle as you join Drs. Robert Asher and Teresa Welles in a search for a lost cure for a ancient killer that makes a reappearance. Modern technology keeps them in communication with the outside world, but it cannot protect them from unexpected dangers they encounter once they reach their destination, a lost city of the Mayan civilization.
