Wild and unruly; that's the descriptive adjective for a main character. But, it's also the name for the Oklahoma Territory. Here is the land rush of 1889 that opened the territory to settlement and left one more blot on the nation. Two if you count the subsequent oil gush. As a story, merely average, but epic in exposure of the underlying history.
"Here is Oklahoma, from the tumultuous Land Rush of 1889 down to modern times. Here is the hard, dangerous, and defiant struggle of the pioneers against heat, dust, thirst, Indians, and the wilderness; the first oil gushing from the parched ground, the incredible fortunes made overnight, the Osage multi-millionaires who startled the world, the amazing, mushroom growth of a skyscraper city in the middle of the prairie. ... The might novel of the opening of the West by one of America's most powerful writers." -- prefatory and back-cover text
