Peters is first and foremost a scientist, and keeps to the facts while injecting portions of personal narrative and light humor. I found it the complete opposite of The Hot Zone, which fuels fear with gory, outright lies about Ebola victims "liquefying in their beds" and leans more toward Hollywood script than factual account. In particular, Peters' account of the demise of Donato was both a sad recounting and an important lesson about safety.
At times the writing can be a little dry, especially later in the book when Peters talks about former time at USAMRIID, but this wasn't entirely unexpected of science nonfiction work.
After so many mentions of events happening up to the early 90s, I couldn't help but wonder why Peters was fixating on this. When I flipped to the publication date at the front of the book, I was surprised that its first printing was in 1997. My bad. I assumed I was getting something newer when I first purchased this, but it just goes to show that one should never judge a book by its cover, no matter how nice the graphic design. That said, the science in the book has obviously aged now and significant advances forward have been made, including development of the first Ebola vaccines. I am not suggesting that Peters' book isn't worth reading, but if you do want to delve into the world of hot viruses, I would start here and then move on to something more recent, such as Spillover by David Quammen, which effectively predicted the Ebola outbreak circa 2014.
Overall, an interesting and informative read for those not already familiar with the topic.
