I've read all the other Sharpe novels, so it was inevitable that I would get round to this one sooner or later.
If you are a fan, you'll probably read it anyway. If not, I suggest you start elsewhere.
Not that this is badly written, but given its position in the chronology of the character (early but not at the start) and that it is the umpteenth book written by Cornwell about his most famous character (Richard Sharpe) I would be hard pressed to say it offered anything new or insightful about the character or the period.
A bit of background might help those who are interested.
Richard Sharpe is a fictional soldier in the British Army during the Napoleonic period.
The earliest novel (so far) is set in India in the 1799 and the latest is set in South America (mostly) in 1820-21, but the core novels and the earliest written are set in the Peninsular war (Britain & Portugal vs. France in conquered Spain) between 1809 and 1812 leading inevitably to Belgium and the fields at Waterloo.
If you can think of a major (or even minor) British military engagement in that time period, Cornwell has written a Richard Sharpe book about it (except the 'War of 1812' ..but it may yet come if he can get Sharpe there and back before waterloo).
This novel is set pre 1809 in the lovely city of Copenhagen and tells the story of the British attack on the city. The device that gets Sharpe there is a plot to bribe the Prince of Denmark into surrendering his fleet to the Brits to prevent the French from getting their hands on it (as a replacement for the fleet they lost at Trafalgar).
I wasn't aware previously that we had attacked Denmark or that we shelled the population of Copenhagen into surrender...not a particularly nice episode in our distinguished past, but given our record in WW2 it shouldn't have been a surprise, so Cornwell gets an extra point for that.
Otherwise it is rather formulaic and while an entertaining enough read, does nothing to challenge the reader or their preconceptions about the lead character. We know so much about Richard Sharpe from the other novels (joined the army to escape poverty, became a sergeant and was raised from the ranks to become an Officer for saving the {future} Duke of Wellington's life in India) that this is just another slice of boy’s own adventure.
I'd give it three stars, because its only for fans of the series.
