Balaclava, Alma, Inkerman, Scutari, Sebastopol. It's strange how just the names of events and places from the Crimean War can still stir up emotions in the twenty-first century. They conjure up images on the one hand of the follies of so-called "glorious" warfare in the name of Empire, and on the other of the selfless dedication of pioneering nurses in adverse circumstances. Katherine McMahon's new book ''The Rose of Sebastopol'' takes us back to that time to view it all through the eyes of Mariella, a lady who at first is quite content to stay at home in England within the boundaries expected of her station in life; while her relatively reckless cousin, Rosa, can't wait to escape her lot by enlisting to assist Miss Nightingale on her mission in the Crimea.
