In These Thousand Hills, the third installment of A. B. Guthrie, Jr.'s Big Sky series, we follow Lat Evans (grandson of Lije Evans from the second book in the series, The Way West) as he negotiates the untamed, raucous world of cattle ranchers in the 1880s. Evans begins as a gentle cowboy, seeking a more prosperous life than his meager upbringing promised. His rise to fortune is a tempestuous one, complete with moral dilemmas and shady characters who would lead him astray. Evans finds prosperity with winnings from a horse race and a loan from a prostitute. But when he realizes his political ambitions may be waylaid by his checkered past, he truly learns the price of compromise.
