I believe the theme in the book I am reading is that despite a crappy start greatness can be achieved. Young Abraham Lincoln starts life on a small rundown farm where he lives with his family of 4. He experiences death at a young age when his younger brother Thomas dies before he was a month old. His mother dies short after that sending him into a dangerous depressed rage. He finds the culprit of her death is a vampire and vows to kill as many vampires as he can. He kills the one responsible for her death and realizes it isn't as impossible as he thought. He begins training himself in preparation to fight the undead creatures of the night.He gets his behind kicked by an old lady vampire. after many years he becomes the vampire hunter he dreams of. Later he becomes president of theses great United states. He is the ideal that humble starts can lead to greatness.
