The Call of the Wild (White Fang) by Jack London

*WARNING* Not recommended for children younger than 13 as the book contains lots of violent parts.

It has lots of educational value about how life was when the Yukon Gold Rush started.

It explains the hard work and struggles that Buck (the main character) had to go through.

There is lots of action and sadness. The story is about a dog that gets taken from home and becomes a sled dog in harsh terrains of yukon canada. 

[Personal note: I read this book as a teenager and again as an adult and both times I realised just how disappointing and in human some species of the human race can be.]
