There’s a town in Montana called Hell Creek. It’s not on any map, there’s no post office, a census has never been taken, and the most permanent structure is a saloon. It only exists because the ramshackle settlement is next to one of the world’s largest dinosaur graveyards. It’s a hard place to live, and a worse place to die. Summer digs are in full swing and thirty-four-year-old graduate student Jack Templeton doesn’t have time for distractions, but when prehistoric predators overrun his dig site, he becomes prey. Hunters from another age stalk the transformed iridium-rich badlands, but the real enemy waits where Jack least expects it. Who will survive the day the dig came alive?
