The Call of the Wild turned Jack London into an overnight literary success and secured him a place among the greats of world literature. While London's publisher was concerned that his gritty adventure story was "too true to nature" for the reading public, he was proved wrong. The first print run of 10,000 copies sold out immediately. The novel about a dog who returns to his primordial roots in the extreme, unyielding environment of the Klondike Gold Rush still draws readers young and old. Scientific debates of its time, as well as London's political convictions, influenced The Call of the Wild heavily, leading to a wealth of possible readings and interpretations. Yet when it comes down to it, the strength and continued appeal of the book lie in its gripping adventure, which transports readers to the beautiful, unforgiving wilderness of the American North. And while many film adaptations focus on the theme of the dog as man's faithful companion, the original is so much more than that: It is a compelling story of survival and a celebration of untamed nature.
