" If you enjoyed The Hot Zone or any other literary non-fiction about diseases or epidemiology, you'll certainly enjoy this. Much like The Hot Zone, but a look at smallpox, so it has more background history than ebola which I found very interesting. WARNING: SMALLPOX IS GROSS. Preston's graphic descriptions don't particularly both me, but this and his other books are not for those with weak stomaches. "
