History/biography is a very difficult genre which all too often gets clobbered by either the Scylla of turgid style, overly dense footnotes and too much detail or the Charybdis of superficiality and crowd-pleasing. Hughes' 'Helen' brilliantly steers herself past both with a witty, engaging and passionate style and ample, but not excess, detail to back up her ideas.
The book is a dazzling exploration of Bronze Age history and, particularly, the role of women in it which is threaded on a figure who is universally known and relevant today. The trick of imagining and pursuing Helen as a real person gives a cogency, life and focus to a field which might otherwise have little or no appeal to a modern non-academic audience. Furthermore, combining that history with an analysis of how views of Helen have changed and developed over time gives an essential cultural context for the whole exercise. All-in-all, easily one of the best history books I have ever read.
