I have two books, The Coming Plague (more than ebola out there to worry about) and The Hot Zone (which is all about ebola), that I read a long time ago that I can recommend. I've got more but those were the two best one. This has been on my radar for 15 years or so.
When I joined a book club years ago we talked about the type of things we like to read and what each of us might bring to the group. I said "how do you guys feel about plagues?". The response WAS NOT enthusiastic..
