The Rule of Reason is a variation on Impulse & Initiative, aka To Conquer Mr. Darcy, and should not be considered a completely separate novel. The first third of the books are close to identical, but after that the plots diverge substantially. In my opinion, Impulse & Initiative is a stronger book, but The Rule of Reason has segments I particularly like, and some readers prefer it. It has the same premise as Impulse & Initiative, but in the library scene at Pemberley, Darcy and Elizabeth make a different decision, leading to very different outcome. Unlike Impulse & Intiative/To Conquer Mr. Darcy, this book contains no graphic scenes.
