He'll make her a bet she can't refuse... Lily McIntire is in the creepiest mansion in town. Alone. At night. Because she's an idiot-and can't ignore a dare from her cocky and infuriatingly hot co-worker, Marcus Black. But she'll be damned if she's going to give him the satisfaction of winning. Marcus has had a thing for Lily for ages, and he has no intention of losing this bet. His plan? Scare her out of the house, and into his arms. Once there, scaring her turns into protecting her and soon after, into seducing her. And his plan is working... Lily is having trouble relegating Marcus to the role of "asshat" as easily as before. He came to her rescue, and he's actually funny. Charming. Sexy as sin on a stick. But Lily has a strict no-love-in-the-workplace rule, and even one night of the best sex ever won't make her change her mind. So she's calling everything off... Surviving a night in the mansion might just be the easy part. Surviving Marcus's increasingly convincing advances is going to take everything she has. Losing is not an option...
