Four siblings. An outlaw father. One purifying fire sparked their thirst for justice.

The Harper name once struck fear in honest folk across the Arizona Territory. Now it strikes terror in outlaws.

Galen Harper's children escaped his brutal reign and forged a new legacy-as Pinkerton agents, U.S. Marshals, Rangers, and prosecutors. They hunt down men just like the one who raised them.

But how does a family transform from shame to honor? From survival to purpose?

Retired Arizona Ranger Shane Harper sits by the fire with his grandchildren and tells them the truth. Stories about Christmas Eve 1880, when he was thirteen and responsible for keeping his younger siblings alive. About the blood-soaked rescue that finally set them free.

And finally, about one night when four siblings chose justice that would echo through three generations.

This is the origin story of the Harper's Justice series-where you'll discover the oath that changed everything.

"When justice is executed, it is a joy to the righteous but a terror to evildoers." -Proverbs 21:15
