If you are looking for a hero, especially if you’re a girl, you might consider Mary Edwards Walker. Born on November 26, 1832, in Oswego, New York, she was a nurse, doctor, woman’s rights activist, abolitionist, prohibitionist, alleged spy, and prisoner of war during the American Civil War. She became the first, and as far as I know, the only woman to win the Medal of Honor for Meritorious Service.
I had never heard of her before. Then today at high school I happened to see a book about her. This proves that heroes are out there; you just have to find yours.
There is a good biography of her life at http://www.biography.com/people/mary-walker-9522110#receiving-the-congressional-medal-of-honor. The photo is from that website.
