All Harper Thompson wants for Christmas is the huge promotion she's worked so hard for--which she should get, as long as her launch of the hip new coffeehouse, Deja Brew, goes according to plan. Jonah Rogers is trying to save his family's coffee shop, Lucky Star, from going out of business, which will be tough with the brand-new Deja Brew opening across the street.

When Jonah and Harper meet for the first time after accidentally swapping phones, their chemistry is as electric as a strand of Christmas lights. He's a tall, handsome, compassionate hunk of engineer, and she's an entrepreneur whose zest for life is very sexy. They love all the same things, like scary movies, greasy food--and most of all, dogs. It's a match made in heaven...until Jonah finds out that Harper's the one about to put him out of business.

Only one coffee shop likely can survive, and a competition of one-upmanship ensues in a battle of the brews. The paws really come out when the local rescue shelter has a fundraiser where local businesses foster dogs, and patrons vote with their dollars for their favorite pup. Harper takes in an adorable old bulldog on behalf of Deja Brew, while Jonah fosters a perky three-legged dachshund for Lucky Star. As the excitement builds for who will be crowned King Mutt and king of the coffee hill, Harper and Jonah must decide if their connection was all steam or if they are the perfect blend.
