Young and innocent Ursa Hollington, by the will of fate, is forced to become not just an impostor, but a doubly impostor. On the one hand, the girl has to play the role of her sister in front of her blind mother-in-law, on the other hand, she also has to save the young Marquis of Charnwood from an unwanted marriage of convenience by portraying his bride! The carnival may be fun, but for some reason Ursa is not having fun at all. Especially when she realizes that she really fell in love with her “fiancé”, fell in love without memory, with all the strength of her soul...
