Out of the white wilderness, out of the Far North, Jack London, one of America's most popular authors, drew the inspiration for his robust tales of perilous adventure and animal cunning. Swiftly paced and vividly written, the novel and five short stories included here capture the main theme of London's work - the law of the club and the fang, man's instinctive reversion to primitive behaviour when pitted against the brute force of nature.
