Despite the cover art on my copy, this is not a western
A hard edged novel of peril and adventure on the western frontier when that frontier was EAST of the Mississippi River. This historical novel splendidly mixes fictional and real people and history of the western frontier area of Southern Illinois, Kentucky, Tennessee, Mississippi and the Ohio and Mississippi Rivers. There are a number of villains but the main ones are the Harpe brothers. Little Harpe and Big Harpe are drawn much as the two infamous murderers, torturers, thieves and America's first recorded serial killers must have actually been.
This is a far flung story which eventually brings all of its diverse characters together. It is not a short book nor is it particularly easy to read. Partly because of the unremitting chronicle of evil and villains which plagued the frontier.
