Ever since she was a little girl learning to make decadent truffles in her family's chocolate shop, Juliet Arabella has been aware of the bitter feud between the Arabellas and the Mezzanottes. With their rival chocolate boutiques on the same street in Napa Valley, these families never mix. Until one night, when Juliet anonymously attends the annual masquerade ball. In a moonlit vineyard, she finds herself falling for a gorgeous stranger, a man who reminds her what passion is like outside of the kitchen. But her bliss is short-lived when she discovers her masked prince is actually Leo Mezzanotte, newly returned from Paris and the heir to her archenemy's confection dynasty.
