Like others, I'm conflicted as to how to review this book. It is well-researched, and approaches the Black Death from many different angles, from microbiological to anthropological to historical. However, the author makes some deeply problematic arguments and frequently takes potshots at other academics in the field in a way that is unbecoming.
I was fine approaching the book as flawed-but-useful up until the chapter on the Jewish pogroms, or the "artificial poison conspiracy," as Aberth re-names it. His takes in this chapter are, to put it mildly, rancid. Other reviewers have rebutted his arguments better and in more detail than I can. His assertions are at best negligent and at worst flat-out antisemitic. From that point forward I really could not bring myself to trust his expertise or enjoy the read at all.
