A collection of stories.
THE WHEELS OF IF turned – and Allister Park spun from our own New York
through a dizzying succession of alternate worlds to New
Belfast... biggest city in the Bretwaldate of Vinland, the country that
might have been it some historical crises had turned out the other
Park's frantic efforts to get back to his own if-world turn Vinland upside down – and create a marvelously inventive and entertaining classic of SF.
In addition to this famous novel, this collection includes "The Gnarly Man", "Hyperpilosity", and four other stories in the inimitable De Camp manner.
