For the past 160 years, giant birds have been reported in the skies above the Black Forest region of northern Pennsylvania. Now, it's up to one man and one woman, to find out where they came from, and where they've gone. Failed Ph.D. candidate and erstwhile assistant museum curator Ian McQuade is rescued by cartographer Alma Del Nephites, after an ill-fated expedition into the Amazon Basin. They travel to meet the enigmatic CEO of a secretive organization, where the two are given the opportunity to seek out proof of the existence of thunderbirds. A madman's journal will lead them into the heart of a 700 year-old mystery, where cutting edge technology designed to locate and identify such creatures will collide with an ancient power that has hidden and protected them for centuries. Ian must face his past, in order to believe in a future that couldn't possibly exist. With lightning in their eyes and thunder in their wings, who will control the fate and destiny of the thunderbirds?

In the U.S. Geological Survey, there are over 100 tribal and 2300 location names, in the United States alone, for a creature that walks in myth and legend throughout the 25,000 square miles of the Pacific Northwest. As a young boy on a family camping trip, 9 year old Ian McQuade encountered one of the giant, apelike beings. The experience changed his life forever, limiting his academic prospects and ruining his professional career. Now, twenty years later, an anthroplogist and a Ph.D. in his own right, Dr. McQuade sets out on an urgent mission for Cyril Pritchard and the Chimaera Foundation in pursuit of Bigfoot, without partner Alma Del Nephites. In the process, two of the greatest mysteries about Bigfoot will be uncovered, in a desperate race against time. One must remain a secret at all costs. The other must be revealed, before it is too late...

Along the coastal waterways of Georgia's tidal marshes, there lives a monster that makes the Altamaha River its home. Over 20 feet in length, with a snakelike head atop its long neck, the Altamaha-ha has been sighted dozens of times by those who live along its namesake. A pregnant female struggles to return upriver and give birth. She is bound by those who captured her before, and pursued by others who already killed her mate for where she can lead them. A place marked as the abode of dragons by the Tama Indians, it is also the location of a treasure buried in the final days of the Confederacy. Drawn to the river and caught up in events centuries in the making, Ian becomes the unwitting pawn in a quest for world domination. He soon learns of his link to the Altamaha-ha, and that he must save it, if he is to save himself. Aided only by a few colorful locals, McQuade must defeat the enemies of the Foundation, before its technology is turned into a doomsday device.
