Query: Written like a technical journal article

When I heard the author interviewed on NPR I rushed out and purchased a copy of the book. What a disappointment! As an avid reader I hate to abandon a book after I start it. I did finish Krakatoa but it was a real struggle - actually more of a challenge to prove I could do it. The book is verbose, written like a technical journal article and is overloaded with footnotes and run on sentences. For a 350+ page book, surprisingly little deals with the actual eruption and aftermath. It's more of a book about the geology, politics, biology, botany, and economic history of Java/Sumatra. Although there are several maps in the book, none of them actually says "this is where Krakatoa was". The author assumes you'll be able to figure it out by reading about a bunch of obsure landmarks and then looking at a map.
