This book is ostensibly about the 1815 volcanic explosion and lava ejection from Java's Mount Tambora, but what really happens in this book is a drowning: the authors positively drown readers in a relentless heap of anecdotes on weather conditions, weather reports, peoples' comments about the weather, peoples' diary entries on the weather, reports on failed crops, explanations of weather phenomena and more meteorological minutiae from that era than you can possibly imagine. The book goes nowhere and at just over halfway through I decided to stop taking any more punishment.
I could not finish this book and I'd only recommend it to serious, serious meteorology geeks--even then with great hesitation.
