The book is very good, has enough information about volcanoes all around the world while also giving a good level of insight about their characteristics such as history and navigation. Additionally, the high-quality images and the introduction to volcanoes (almost EVERYTHING about volcanoes) is a cherry on top!
In conclusion, it's dirt cheap and informative at the same time. This book is why I somehow want to pursue geology or volcanology. You must buy this book ;)
