The call of the wild (global classics) -

After reading “The Call of the Wild”, I've come to realize that it would be difficult living on the Klondike in the Yukon. The weather is very cold and life is very hard there. You’ll understand better as I explain the story of the book to you.

In this book Mercedes, Hal, and Charles, a group of very inexperienced and even less equipped city people, to depict the probability of doom to those who do not adapt. While in Skagway the three have no idea what the Klondike holds. The well dressed well fed team wants nothing but riches and fame. In their effort for time they purchase the now exhausted dog team, which Buck leads, to take them to find the gold.

Even during the beginnings of their journey they show their expected doom. Mercedes, the most shrewd of the bunch piles load after load on the sled. Onlookers laugh at the sight, telling the them that the sled will tip. In their pride the warning goes without notice, soon to find the now moving sled scattered across the street.
