"Mr. Raine gives us early Colorado in full and persuasive detail. We see Denver in 1860, with its shanty-lined streets, its brutal citizenry, and its primitive justice. The picture is decidedly stimulating in its reminder that the pioneer days of Colorado are within the memory of men and women now living. We in the snug East need to have our memories thus jogged. The novel does more than that, however, for in it we get an unpretentious, satisfactory adventure story, in which we find the usual outlaws, stagecoaches, and saloons. In addition, there is the love of a lusty lad for a beautiful girl. We find nothing remarkable in the plot, to be sure, but our common sense suffers no assaults. Colorado is, in short, agreeable adventure set against a splendid background." —The Saturday Review
