Mr. Cornwell gets better with every book. As this book starts, Sharpe is about as far down as it is possible to go and ready to give up on the army. Then a secret mission to Denmark gives him a chance to remember that his great talent is as a soldier.
The description of the bombardment of Copenhagen is vivid and visceral. And Sharpe's adventures are absorbing and real.
If you are looking for a bit of military adventure and swashbuckling, you can not do better. I do believe this is the best Sharpe book I've read (to date).
