"The Call of the Wild" by Jack London is a classic adventure novel set during the Klondike Gold Rush of the late 19th century. The story centers on Buck, a powerful St. Bernard-Scotch Shepherd mix, who is stolen from a comfortable life in California and sold into the harsh world of sled dogs in the Yukon wilderness. Faced with brutal conditions, Buck must learn to survive and adapt, shedding the comforts of civilization and embracing his primal instincts as he navigates life among both men and competing dogs.
