For this Throwback Thursday I recommend: The Call of the Wild by Jack London.
The adventures of an unusual dog, forcibly taken to the Klondike gold field, where he eventually becomes the leader of a wolf pack.
Originally published in 1903, this classic was quickly adapted into a movie in 1923, and has been adapted into a movie several other times since then. This classic is for readers who enjoy more tense drama, it is not a standard happy animal story.
You can find The Call of the Wild in the Juvenile Fiction section at J LONDON.
