From USA Today and #1 Amazon Bestselling Author Pippa Grant comes a witty road trip romcom performed in duet narration about a billionaire on the run and the last woman on earth he wants in his passenger seat…

That didn’t turn out the way I planned it.

All I wanted was five minutes with Oliver Cumberland to explain to him that proposing to my sister—again—is a bad idea.

Instead, I’m now trapped in his car, on a cross-country road trip I didn’t anticipate, attempting to talk the grumpy billionaire out of something much, much worse than an arranged marriage for business purposes.

I don’t care if Mr. Square Jaw McMoneyPants wants to give away his entire fortune and disappear to live out his life working the popcorn counter at a movie theater or whatever in Podunk, USA.

But I do care that dozens of non-profits will lose their funding without Oliver in charge of his family’s empire. After all, I work for one.

I have to convince him to go home.

But by the end of the first week of our (mis)adventure, one thing is becoming obvious:

Oliver refusing to return home is the least of my problems.

The fact that I’m starting to fall in love with my sister’s ex is the real issue.

The Grumpiest Billionaire is a runaway billionaire road trip romance featuring a man who’s tired of taking responsibility for everyone around him, a woman who’s made a lot of mistakes while on a lifelong mission to save the world, and a slew of unintended consequences that prove no good deed goes unpunished.

Tropes include: Enemies to lovers, road trip, small town, sibling's ex, and runaway billionaire
