It turns out that I have already listened to this book which, apparently, is where my knowledge came from...yes, it was a great book.
Oh no! Hope you didn't have to pay for it twice!
I knew almost nothing of President Garfield prior to reading that book. It was in my ship's library and looked interesting. I also like history so I grabbed it and then couldn't put it down once I started. It read like a page-turning thriller, except that we knew how it would unfortunately end.
