I need someone to check over this and make it more formal, please.

The call of the wild, on the surface, is a story about Buck, a four-year-old mixed dog that is part shepherd and part st. Benard. More importantly, it is a naturalistic tale about the survival of the fittest in nature. Throughout the novel, Buck proves to both himself and others that he is not only fit but the fittest. Buck overcomes many challenges with the goal of becoming the leader, the best. During the story, he learns the rules and codes of the north, then makes his own. Though it seems like buck is the only focal point in the book, there is a larger meaning behind the story, such as the fact that Buck is merely a proxy of Jack London himself. The general theme of the story is wild vs. civilization and bucks internal conflict with the choice between the two. Throughout the chapters, Buck is conflicted with his choices but ultimately chooses the wild. I believe one of the most fascinating parts of the story was when Buck became softer around Thorton and seemed to let his guard down more than he ever has in the story beforehand. This situation shows Buck leaning towards civilization more rather than towards his instinct and natural urge of the wild. As I said before, one of the most important parts of the book is Buck's internal conflict between his two choices; civilization or wild? Jack London is an extremely skilled writer and did a wonderful job at creating a mental picture of the cold and harsh North to his audience. It is to be made a point that Jack London doesn't write for any audience in specific, he writes to the world, not a certain group. His book is not only interesting to adults but it is also interesting to middle schoolers and high schoolers who may be reading it in their language arts class. In short, Call of The Wild is a book anybody would enjoy and I highly recommend reading it.
