This novel continues Scarrow's fictionalized version of the lives of Napoleon and Wellington. It follows Napoleon's time as a general in Italy and Egypt and his rise to become first Consul. For Wellington, it covers his time in India. The book is more military focussed than the first.
One odd feature is that the story covers ground here that has been in the Sharpe novels. A couple of scenes felt slightly out, because I "know" that this was the place that Sharpe first met Wellington, or that he was present at that event, and so on.
