To preserve the future of humanity itself mountaineer Roy Graham must descend deep into the species' cryptic past. In the most perilous adventure of his lifetime he confronts Stone Age beings who set brutal, brilliant traps. Discovery of pre-hominid DNA and geological tracking over millions of years are only some of the skills Graham and his team must use to comprehend the enemies they desperately need to outwit. It's all part of author Philip E. Bartow's wildly inventive science fiction adventure Triassic. With plot twists as ingeniously connected as a strand of DNA, Triassic probes deep into science, technology, and history to consider what it really means to be human, all the while delivering jolt after jolt of "can't put this book down" action and intrigue. In lush, uncharted South American canyons, military helicopters equipped with sensitive technology are disappearing without a trace. When aerial surveillance reveals nothing, the only way adventure pro Roy Graham can mine the truth is to enter the jungle on foot. When his friend Mark Stark draws him into this seemingly suicidal mission, the last thing Roy expects to land among are Stone Age creatures, or Mapinguari. As Roy and his team dig into the deep recesses of the canyons, employing sophisticated DNA identification technology to reveal the expansion of pre-human beings, their discoveries unearth horrifying connections with our own species. At the same time, Roy discovers deeply disturbing aspects of some modern individuals in his own team. Triassic delivers breath-taking physical prowess and formidable intellectual puzzle solving to keep readers tightly engaged with both plot and characters page by page.
