Some of my family members died in the flu epidemic of 1918, so I've always wanted to learn more about it. This was an interesting book, and the author did a good job of showing the types of things that might happen when a healthy town tries to keep out the unhealthy, and the difficult choices that might result. Although I am a progressive person, the installation of characters with 21st century progressive values into an early 20th century didn't quite ring true. Nonetheless, it's worth a read.
