Eva Stachniak's beautifully researched historical novel about
Catherine the Great is a big juicy read. Told from the point of view of a young woman who enters the Winter Palace as a seamstress and becomes a spy (a "tongue") on behalf of the young woman who will one day be the Empress of All Russia, the book is filled with sex, intrigue and treachery.
The story is told by Barbara (called Varvara in Russian), a Polish book-binder's daughter who turns out to have a natural knack for espionage, although her lessons in it include deflowering at the hands of the spymaster, Alexei Bestuzhev, the Chancellor of Russia. The two women whose lives bookend the story--the ruthless
Elizabeth (daughter to Peter the Great) and Catherine--seemingly could not be much different but as Varvara realizes, Catherine has her own agenda and her own methods.
There is love in the book, and a fair amount of sex, but that aspect of the story does not drive it. Probably the most intense man/woman connection in the entire novel is the one between Varvara and her spymaster, and in later scenes, when he tells her some harsh truths about her situation, we know that he is right because we're told so in Catherine's own words at the very beginning of the story.
If you're looking for an historical novel that's long on detail and layered with great observations, you should take a look at
The Winter Palace.
