Robert K. Massie clearly loves his subject, and this book is an enthusiastically-written history of the personalities, and technology, behind the steady drift of Europe to World War 1. The style is such that reading the book is like encountering a clubbable historian in your local pub. Some people may not like this method of writing, but I found it a refreshing change, and I enjoyed the anecdotes about some of the personalities, like Lord Salisbury entertaining a lunatic unawares, in his personal railway compartment. For a non-specialist but interested reader, like me, this book was an excellent read.
