While You Were Sleeping but make it Brother's Best Friend and a Red Coat in New York. Honestly maybe a 3.5 but the whole fake husband felt real creepy to me especially in the puritan culture of a regency romance.  IDK.

LOL forever at my dad buying this for me at The Ripped Bodice on our trip to LA because he saw the title and said "Oh look Katrina, it's you!"
