.. . but it's a pretty short "book".
It was worth reading but I think you'd learn more from Wikipedia.
If you knew nothing about "the Black Death", reading this will give you a bit of background but you'd never call it an in-depth study.
Not worth the download for history buffs. If I had taken time to read the description on Amazon, I would not have bothered with this "book" (but I downloaded it & read it in a few minutes).
KInda like you're expecting a meal but get a bite of a candy bar instead.
