This book is in a genre I like (microhistories) but I found it pretty dull reading. It's basically a very superficial history of "the world" (mainly Western Europe) that posits malaria to be the cause of pretty much every world event. I'm sure there's some truth to this, but the plodding military metaphors and oversimplifications really started to wear on me.
I haven't read it, but a recent review (https://lrb.co.uk/the-paper/v42/n11/steven-shapin/drain-the-..., possibly behind a paywall) suggested Sonia Shah's The Fever to be a better book on the topic.
