The Winds of Autumn — Jim R. Woolard

Jim R. Woolard's classic western of a family torn apart by a savage, untamed territory, and their relentless struggle for survival -- and revenge . . .
 
Deep in the Ohio Valley, the Tyler family laid claim to a new life. But one deadly evening  changed everything. Under a moonless night, the family is beset by rampaging Shawnee. In the red storm of bullets, arrows, and knives, Blake and Blaine Tyler emerge bloodied but alive. But their parents have been brutally murdered. And their sister, Sarah, is the victor's spoils for a war party long gone.
 
Undeterred, the brothers set off across the Ohio River. Two against one embittered nation makes poor odds. But revenge has a way of getting the job done . . .
