Douglas Preston is one of my favorite writers but he has really been slipping lately. Maybe its just me but i don't understand the excitement about finding dinosaur's skeleton. And there is actually a conspiracy and people get killed over that? Oh, please! I can also do without all the descriptions of the canyon and mesas. It seems like there is one every other page-one time would have been enough. I love suspense of his other novels but this one definately a lemon. If i started reading his books with this one, I wouldn't even try reading anything else. I think he is running out of ideas
