The cowboys who work on the ranchlands of Montana expect more than their fair share of trouble. One of them is Mike Wire, a former homicide detective. Mike is about to learn murder and mayhem can happen under Motnana's big skies, too. Beneath the earth lie enough dinosaur fossils to fill several museum collections---and make a fortune for whoever claims them first. Soon he will have to combine everything he learned as a cop with everything he knows as a cowboy to protect the people and the land he could never live without.
