Weekend Agreement by Barbara Wallace
Cynical billionaire Daniel Moretti works hard, plays harder, and has one ironclad rule. Never trust a woman. Bad news for historian Charlotte Doherty who shows up at exactly the wrong time. Like every other woman in Daniel's life, Charlotte wants something from him–the deed to her family farm. Daniel agrees, but only if he gets something in return: Charlotte's company for the weekend!

Daniel has no intention of honoring her conditions, but after one weekend with Charlotte leaves him hungering for more, he can't help wondering if she could be the exception to his unbreakable rule...
