I'm just starting this book on audio and love it so far. Great narrative writing style is bringing this nonfiction to life. I have to admit that I know next to nothing about James Garfield, so this is captivating and educational for me. The author is using the 1876 World's Fair in Philadelphia to place the reader within the time period, examining new inventions (Bell's telephone), the state of the medical field (antiseptic? whatever), and fun tidbits like the US's lack of a national anthem. I'm already worried about being sad at the end.
