The Call of the Wild

Buck, a sturdy crossbreed canine (half St. Bernard, half Shepard), is a dog born to luxury and raised in a sheltered Californian home. But then he is kidnapped and sold to be a sled dog in the harsh and frozen Yukon Territory. Passed from master to master, Buck embarks on an extraordinary journey, proving his unbreakable spirit...
First published in 1903, The Call of the Wild is regarded as Jack London's masterpiece. Based on London's experiences as a gold prospector in the Canadian wilderness and his ideas about nature and the struggle for existence, The Call of the Wild is a tale about unbreakable spirit and the fight for survival in the frozen Alaskan Klondike.
No other popular writer of his time did any better writing than you will find in "The Call of the Wild". —H. L. Mencken.
Few men have more convincingly examined the connection between the creative powers of the individual writer and the unconscious drive to breed and to survive, found in the natural world… London is in and committed to his creations to a degree very nearly unparalleled in the composition of fiction. —James Dickey
