Very interesting; on the surface it appears like a typical romance, but it turns out the secret playing out between the heroine and hero is an unusual and refreshing one! There is science! What makes it particularly refreshing is the the "rake" isn't very rakish. Sure, he has his dalliances, but he's gentlemanly about them (they are always mutual and light), and meanwhile he harbors a long-standing unrequited love. He enacts a long-standing public deception as a result of his love that gradually undermines his self-confidence, because he honestly believes the woman he loves is so much smarter than he is, which in actuality, he has been her partner all along.
