Jingle Belle Knowles is excited about the opportunity to write a Christmas jingle for a new restaurant in Pohono, Oklahoma–until she meets the company's cocky PR man. Despite an immediate personality clash with much-too-handsome Italian Nick Santini, Belle finds herself irresistibly and unacceptably drawn to her insufferable client. Nick isn't pleased about working with the lovely jingle writer. But with a grand opening date just two weeks before Christmas, he and his brother need something to draw shoppers off the streets and into their Tuscan-themed restaurant. Given Belle's stellar reputation, Nick makes up his mind to grit his teeth and get through the project. They're both adults. They're both Christians. And they're both determined to make the project a success. But when a passionate, self-assured, hard-headed Italian butts heads with a stubborn, auburn-haired, confident Irish spit-fire, the results could make for a highly chaotic Christmas season.
