This book is from the Horrible Geography series and is a lot of fun. It is a guide to volcanoes with the gritty bits left in. You can read the diaries of volcano survivors, get clued-up with the spotter's guide to eruptions, plan an explosive holiday with the volcano vacation guide, marvel at red-hot volcanic rocks the size of cars. It has excellent diagrams, funny cartoons and is a painless way to learn about natural disasters. There is lots about Mt St Helens, Pompeii and Krakatoa.
