Killing Lincoln by Bill O’Reilly is a great book. I think it is inspiring to read history books that are written in the first or second person. Gingrich has written several books like this, but keep in mind these books are fiction and speculative at best. But I think it is a great way to learn about history with this genre or type of writing. It places you at the scene of the killing of Lincoln and Booth. At the end of the day you may not remember all the names, but you will remember a few basic points. Lincoln was shot a few days after General Lee surrendered to General Grant. And Booth was probably nuts fed by the money from the confederates. There are numerous conspiracy theories you can delve into but think about the stupidity of Lincoln and the waste that can be summed up by the words: The Civil War.
