The Black Rifle (Perry County Frontier series);

The Pennsylvania frontier of 1754 could seem too deadly to survive. War parties swept from the protection of mountain strongholds to kill and destroy.
Lured by land ownership, young Jack Elan moved his small family west of the Susquehanna River and beyond civilization's protection.
The band of Toquison of the Shawnee, known as The Heart-Eater, discovers Elan's cabin, and battles to the death begin.
The Black Rifle speaks of Elan's dramatic survival and his soul-devouring efforts to become a frontiersman skilled enough to seek out and destroy the merciless the Heart-Eater.
To learn, a special mentor is essential. That teacher is Rob Shatto, the feared and respected borderer called Arrowmaker who is known throughout the tribes.
A special weapon is required. That "Force Multiplier" is The Black Rifle. Elan calls his Pennsylvania longrifle "Death Giver." The two-barreled flintlock lives up to its name.
