"La Princesse de Cleves" is among the most scrupulously accurate historical fictions in literature. It is also arguably the first historical novel ever written and one of the earliest novels in any language.
But is a classic in Mark Twain's sense of the word, the sort of book everyone wants to have read but nobody actually wants to read?
I agree with another reviewer that this isn't beach blanket fare. Readers of early English literature will find it more palatable than Samuel Richardson's "Pamela" and better plotted than anything by Defoe. Although Mme. de Lafayette is not the first important female writer in French - Christine de Pizan comes to mind - this highly original work outdoes Aphra Behn, Fanny Burney, or any other English woman before Jane Austen.
If those comparisons bring a sparkle to your eye then prepare for a treat. The central figure is a sixteen-year-old girl fresh from a sheltered childhood in the countryside when her mother decides to deal for a prestigious son-in-law. Except for the fictional protagonist every figure in this late Renaissance setting is historically accurate. The jousts, the love affairs, the betrayals, and the shocking death of one pivotal figure all happened. De Lafayette presents the French royal court at its most glamorous, then peels away the facade to reveal ambitions that corrupt or destroy everyone who remains in their spell.
Women's fictions from this era were expected to be love stories. This one succeeds at that well enough to woo modern readers while it levels a scathing attack on the French aristocracy in the tradition of Moliere.
