A billionaire single dad, a nanny who can't afford to fall for him, and a house where keeping it professional gets harder by the day. This steamy nanny romance serves up grumpy-sunshine banter, forbidden attraction and a hero whose soft side ruins all her rules.

He Needs a Nanny. She Needs the Money. The Rules Never Stood a Chance.

Never fall for a rich, grumpy billionaire. No, literally. We collided in the park, and I fell right into his sculpted biceps.

I've never been so turned on by someone so arrogant. Yet there I'm, falling for the city's most eligible single dad. To make this story even more cliché, he asked me to be his new nanny.

I know. Cute nanny falls for hot billionaire with abs. I thought it was stupid too, but I have a mother with health issues, and money doesn't fall from trees.

That's okay. I can totally keep it professional. Even when he walks through the hall shirtless. Even when his hand accidentally brushes against mine. Self-control is my middle name.

Then I see him swinging his little girl around, tending to her every need, and my heart is done for.

Keep it together, girl. Your mother needs you. Because if I fall any further, it won't just be my job on the line. It'll be my heart.
