Holly Winters owns the jolliest holiday shop on Main Street and this season is shaping up to be the best yet. The only pit in her figgy pudding? Declan Gallagher, the owner of the hardware store next door. He's the scroogiest man in all of Mistletoe, Idaho. Then Holly's revenge prank escalates into an all-out war with her Grinchy neighbor, and the situation turns sticky when she realizes she needs his help. Declan can't believe the nerve of his oh-so-cheerful neighbor hiring him to set up her holiday lights display, but the money is too good to pass up. Despite his utter loathing of excessive decorations, he throws himself into getting the job done, only to encounter sabotage at every turn. To his astonishment, Declan finds himself championing the very woman who used to get under his skin. Then one rooftop kiss has him thinking maybe the season's traditions aren't as heinous as he believed. Declan's heart has grown three sizes since Holly came along, but how can he admit he's falling for the one woman he shouldn't want?
