January Girl by Mari Carr

She’s sleeping with the enemy…

After a nasty break-up, Caitlyn Wallace takes a year off from dating to focus on her career. The hiatus is working perfectly until she comes face to face with Lucas Whiting, the uber-rich, cutthroat businessman who is not above using questionable means to acquire something he wants. He wants Pat’s Pub and he’s not taking no for an answer. Caitlyn should despise the arrogant, cocky man for threatening her beloved family’s business, but there’s something about Lucas’ sexy, dominant nature that has the hidden submissive inside her trembling with desire.

What seems like a run-of-the-mill real estate deal to Lucas goes off the rails quickly when he meets the beautiful granddaughter of Pat’s Pub. Lucas never mixes business with pleasure, but that rule is quickly broken. One date turns into two and soon, Lucas and Cait are thrust into a steamy affair neither of them is prepared for. One that forces them to choose between family loyalty and love.
