This sequel to Zane Grey's enormously popular Riders of the Purple Sage picks up ten years after the events of the previous novel. Tragedy has befallen the community of Surprise Valley, and changing views among the largely Mormon populace have begun to create rifts in the community. The Rainbow Trail includes plenty of the adventure and romance that fans of Zane Grey's work have come to love.
2) Betty Zane
The historical novel Betty Zane was famed Western writer Zane Grey's first published book. The plucky protagonist was an ancestor of Zane Grey who fought ferociously during the Revolutionary War, serving as a key go-between during several battles against the British and their Native American allies.
Though Zane Grey is often associated with novels about the American West, many of his early works are historical fiction centered on the Ohio Valley towns where Grey himself grew up. The Spirit of the Border is a sequel to the earlier novel Betty Zane. The book offers a fictionalized account of the exploits of Lew Wetzel, a pioneering figure who fought for the protection of early settlements in the Midwest.
