Falcon MacCallister's father, Jamie Ian, was a legend in the West, but Falcon's quest for justice has driven him onto what many consider the wild side of the law.

The man is Teddy Roosevelt, the original Rough Rider himself. Soon Falcon and Teddy are entangled in a web of robbery, kidnapping and murder that will lead to Falcon's trial on manslaughter charges.

 The Oklahoma Panhandle is 100 miles of lawlessness and danger: a no-man's-land designed to separate Texas from pro-Union Kansas.

Behind them lies a scene of horror left by outlaws who've massacred the boy's parents, as well as the settlers in a small wagon train.

Falcon is going to get those Gatling guns back — before they kill the wrong people. 

The adventure begins for Falcon MacCallister in the town of Tombstone, where his new-found friend Doc Holliday gets an invitation to a dance of death at the O.K. Corral.

His warriors are bent on the slaughter of every man, woman and child they encounter on their way to a war council with Chief Gokaleh, better known as the infamous Geronimo.

In Pecos Valley, New Mexico, a cattle war has erupted, pitting rancher against rancher across a once-peaceful land.

His victims called him Billy the kid. McCallister calls him a bad risk. But in the deadly gamble of the Lincoln County War, placing your bet on an outlaw like the Kid is the only game in town.

And he sentences them to death — the MacCallister brand....

He stands six foot three and is heavy with muscle. Just like his father, Falcon literally doesn’t know his own strength. And like his father, Falcon is quick on the shoot. Lightning quick.
