Billionaire. CEO. Single dad.And, apparently, my date to Manhattan’s most exclusive ball.I thought my invitation was a birthday present from my best friend.The dress, the limousine, the red carpet… I thought they were meant for me.That was mistake number one.Then my date arrives, all gleaming cufflinks and tousled hair, steely blue eyes and a body honed to masculine precision.Arrogant. Charming. Panty-melting.And melt, they do. Hanky-panky with a rich hottie in the back room of the event I’m crashing?Don’t mind if I do.Listen, don’t judge me. It’s my birthday, remember? Nothing that happens tonight counts in real life.Ha.Right.That’s mistake number two.Because the next morning, I start my new job as the nanny for a high-profile client.And my new boss, the owner of this swanky Manhattan penthouse, and the father of these two adorable hellions?Yup. Mr. Hanky-Panky.But the biggest mistake of all?Staying with him.Working for him.Letting my guard down, falling for him...And crashing. Splat.Oh—then I find out I’m pregnant.
