I think that if you are interested in Lincoln's political life this book doesn't really portray his political life, it tells the story of him being assassinated and the scheme that John Wilkes Booth used for killing Lincoln and getting away with it. I think the most interesting thing I learned is that John Wilkes Booth wasn't working alone, he and two of his friends went out to kill other people, too. He sent someone to kill the Vice President and another person to kill Seward. The reason why I think we don't really know about the other two is because the person who went to kill the Vice President got drunk (I think that is the only time that drunkenness is okay) right before he was going to kill him so he didn't. Also the person who was trying to kill Seward only severely injured him. I think my favorite (Well, if it weren't in real life) thing is that Booth shot Lincoln during a "laugh line" so some of the people in the theater didn't know that Lincoln was murdered. A lot of people though it was all just part of the show.
I think that if you are a person that likes fantasy or just general fiction, you will like this book because it's told from a point of view of a fiction book.
I hope you like this book as much as I did!
