It was supposed to be a fake date.
It turned out to be true love.

My assignment is simple. I’m the fake date of billionaire Alexander Maddox for the weekend. My job: to attend a Hamptons wedding with him and convince all the heiresses and socialites competing for his attention—including his ex, who happens to be the wedding planner—that he’s very much taken.

Alexander Maddox is the oldest of the four Maddox brothers, Manhattan’s most eligible bachelors. He’s also the CEO of his family’s legacy investment empire. Loaded beyond belief. And, according to rumors, sexy as sin. But this is strictly a business arrangement.

It’s also an excuse for me to get out of town for a few days. I didn’t exactly mean to break into my estranged father’s house and accidentally discover his offshore bank account details. Or to leave those details lying around where my hacker of a little brother with a serious vendetta might find them. He covered his tracks, he said, but we both know it was never going to be that easy.

My plan: to lay low, spend the weekend by the pool, play my part like I’m an Oscar nominee and hope the little incident blows over by Monday morning.

But my weekend doesn’t go according to plan. Alexander Maddox turns out to be the most infuriating man I’ve ever met. And also the hottest—so hot, in fact, that I end up giving him much, much more than I bargained for.

When the banking incident turns out to be a tiny bit more serious than I imagined, things get complicated. But by then I’ve already cashed in my V-card with the sexy billionaire and made a run for it—or at least tried to.

How do I get myself into these messes? And how did I let myself get knocked up by a possessive grump who suddenly seems to think I’m his one and only?

Against all odds, I think he might be right.
