I thought a one-night stand with the hot silver fox would be a no strings attached distraction. When he walks into my office the following morning, I learn he is a billionaire planning a takeover of my family's company. Scratch the one-and-done plan. It turns out he's cold and cruel and has an old score to settle. There's no way I'm letting this grump have the best of me. But the way he looks at me sends shivers down my spine. And when he touches me again, I lose all reason. He stirs more than my temper, and I can't forget his deep growl that lights me on fire. Then I find out he's a devoted single father. He gives me a taste of the man he could be and a glimpse into a future we could have together. If only we could let go of our past... Grumpy Single Daddy is a standalone, super steamy billionaire, age gap, enemies to lovers romance with a satisfying, swoon-worthy happily-ever-after.
