He's a notorious bachelor and the heir to a billion-dollar conglomerate. But he won't get the keys to the castle until he finds a wife. That's when he proposes the deal of a lifetime with a sparkling rare diamond . . .

I just arrived in London to close a business deal with my friend's brother-in-law's family firm. All I want to do is take my company to the next level. But Kent Bonnaire, the bold, cocky financier, has other ideas. If he's not engaged by Christmas, the board will vote to give the big-boss position to his arch-nemesis. And he won't let that happen.

Kent promises to sweeten my business deal if I agree to stay in London for Christmas and sport his grandmother's rare royal engagement ring. It definitely doesn't hurt when a billionaire owes you a favor. Especially when he has a brilliant mind, a billion-dollar smile, and the sexiest dimpled chin I've ever seen. So I said, . . .

Yes! A billion times yes!

We not only have to keep our arrangement a secret but now we're forced to work one-on-one on my million-dollar deal by day and sip wine by the Christmas tree in his penthouse by night. How can we get any work done when we're stealing steamy glances across the conference room table? Not to mention, his staff's continual interruptions about finding me a wedding dress fit for a princess.

But there won't be a fairytale wedding.

And if Kent's father finds out I'm also the firm's client, there won't be a deal for my company either.

Surrounded by his family at the height of the holidays, this whole thing could go bust. Everything's on the line. Including my heart. Now my fake fiancé may have to risk it all to keep his word . . . and me.
