High-risk securities operative Holly Milano usually prefers to work alone. Having a partner is, well, annoying. Case in point—her current assignment with Kane MacMillan. They're working undercover in high society to retrieve a priceless diamond necklace.

And Mr. Plan Everything is seriously cramping Holly's fly-by-the-seat-of-her-sexy-pants style.

Kane takes his job seriously, and he knows from experience that working with Holly usually ends in disaster. Their conflicting approaches could destroy their cover—or worse, get them killed. But when they're forced to pose as an engaged couple, neither Holly nor Kane are prepared for the possibility of an unexpected attraction...or that they're now putting their lives and their hearts on the line.
