Juliana Fiori is not a typical Englishwoman. She's bold, impulsive, and a magnet for trouble, always speaking her mind and indifferent to societal approval. Her scandalous nature makes her the talk of London—something The Duke of Leighton, Simon Pearson, wants to avoid at all costs given his focus on maintaining his pristine reputation. However, when he finds Juliana hidden in his carriage one evening, his world is shaken. Despite his intentions to uphold propriety, Juliana challenges him to admit that even a seemingly unflappable duke can be prone to passion.
