The Call of the Wild (1903) is the masterpiece of Jack London, one of the most intense adventure novels in world literature. The story follows Buck, a domestic dog torn from his peaceful life in California and sold to work as a sled dog in the frozen territories of the Yukon during the gold rush.

Amidst extreme hardship, hunger, and the law of survival, Buck discovers both the brutality of man and the power of nature. Little by little, his ancestral instinct awakens and leads him through a profound transformation: from a domesticated animal to a wild creature, free and master of his own destiny.
