Jack London 
The Call of the Wild & White Fang [EPUB ebook] 

‚The Call of the Wild & White Fang‘ by Jack London is a compelling exploration of the harsh realities and stark beauty of the wilderness. Published in 1903, ‚The Call of the Wild‘ follows the journey of Buck, a domesticated dog who is thrust into the wild Yukon territory, where he must learn to survive and reclaim his primal instincts. In ‚White Fang, ‚ published in 1906, a wild wolf-dog hybrid faces the opposite journey, gradually learning to trust humans and adapt to civilization.
