The Legend of Jack Donovan by Terence Newnes

After Jack Donovan's parents are killed in a raid on the Oregon Trail, he's brought up by the wagon train scout: half white, half Sioux.

At the age of thirteen, Jack is a drifter, until he rides into the Double M ranch in Cedar Creek. The legend of Jack Donovan begins here, when he takes down rustlers and a glory-hunting gunslinger.

Now, returning from the civil war, Jack finds that a carpetbagger is trying to take over the Double M. Faced with Jack and the Bailey brothers, the carpetbagger has hired some of the fastest guns in the West to win the Cedar Creek war.

But what he doesn't know is that Jack is the fastest gun of them all.

THE LEGEND OF JACK DONOVAN is the first book in the Bailey Clan Westerns series, set in the harsh mid-19th century American Frontier.
