This book was really easy to read, despite the subject matter. (I read it before going to bed a couple of times and had to keep reading for a while longer so I wouldn't have that in my head when I was falling asleep or, worse, actually asleep.) Incredibly grizzly and awful stuff, so if that sort of stuff even kind of bothers you I wouldn't read it. 
 They have a chapter on 9/11, which was absolutely visceral. She was one of the MEs who dealt with the bodies from the Twin Towers and the descriptions of it, particularly around the time of the attack itself, really brought back the feeling of that time. (To be clear, I'm not American, have never been to New York, but I remember when it happened, as I'm sure most people do.) The author's boss was at the site when one of the Towers fell and his description of it was horrifying. 
 So, you know, fair warning.
