This is one of those books I'd actually worried about picking up since I'd seen it in an airport bookstore. Glad I did though (I have become terrible at cruising bookstores, taking photos of book covers and then grabbing them off of Amazon later, if intrigued.). While flawed, it is a fascinating read.
It feels incomplete somehow without a modern updating of how badly malaria currently affects the world (and how little clue most North Americans and Europeans have of horrible a disease it is compared to every other killer on the planet.). I think I personally would have focused more on malaria and how the cinchona tree and
Jesuit powder managed to hold back the tide against it for a while, before the parasite began to adapt to synthetic equivalents like chloroquine and the like.
