Kissing Under the Mistletoe (St. Helena Vineyard #1)
Marina Adair

But she soon tumbles back down to earth when she learns that her new boss is none other than Gabe DeLuca, the scorned wife’s brother. Gabe wants nothing more than home-wrecking Regan Martin out of his life, his sister’s world, and his family’s business. Mostly, he wants the lush beauty out of his head. Yet his attempts to run her out of town have him thinking twice, especially when he sees that Regan may hold the key to tracking down his sister’s stolen start-up capital. Even worse for Gabe, Regan might just be his Christmas wish and hold the key to his heart.
