This book describes the events on the day of 28 June 1914, when the heir to the throne of the Austro-Hungarian Empire was assassinated in Sarajevo. This day had enormous consequences as it led to Austro-Hungry declaring war on Serbia and, through a complicated system of alliances, drawing the rest of Europe into the First World War. The book recounts the run up to the assassination, before describing moment-by-moment how it was carried out. It then goes on to look at its legacy and asks if it hadn't happened would the First World War have been avoided and the whole of 20th century history been different?

Throughout the book moment-in-time panels bring a sense of immediacy to the reader by using eye-witness accounts of certain events. Coupled with large and impactful photographs these really bring the subject to life.
