Dangerous Liaisons (Les Liaisons dangereuses)
The 18th century's great novel of sexual politics. A love story embedded in a game of manipulation, where the manipulators discover too late that they've been playing for real stakes. Valmont's love for Madame de Tourvel is his first honest feeling, and it is exactly the vulnerability his game cannot afford; Merteuil courts the same danger. The darkest and most honest book on this list about the relationship between love and power.
Letters from the Marquise and Valmont carry the novel; letters from the convent-educated ingenue and her earnest suitor are the ones readers admit to skimming. One reviewer says the “letters are very samey,” arguing “absolutely nothing changed throughout those letters” despite the page count, and another writes that “other characters seemed desperately artless” by comparison. The constant reorientation to a new letter-writer kills momentum for readers who just want the plot to move, and a second reader ends up “hoping the writer would get to the point.” Modern readers also flag that several of Valmont's conquests read as coercive rather than charming, and the tidy, moralistic ending feels more like a nod to convention than an earned resolution.
The case for it and the rest of the canon open with Pro.
