Grump Daddy: An Enemies to Lovers Ex’s Brother Romance

by Ellen Young

My boss is my ex’s brother and convinced I’m a spy. So obviously, fake-dating him is a perfect idea.

I design luxury spaces for billionaires with big egos. But none of them compare to the size of my bosses’, Dorian Thorne.

He’s broody, built like sin and dead-set on believing I’m reporting to his brother. Who also happens to be my ex.

When I fall off a ladder and land in Dorian’s arms, he acts like I ruined his day.

Then he “frisks” me for listening devices. And my traitor heart reacts like we’re in a romance novel.

Suddenly, I’m caught in one compromising situation after elevator, closet… you name it.

When his mom catches us in the act, we’re forced to pretend we’re dating.

It’s all fake—except for our chemistry.

The kisses are toe-curling.

And the way he says my name in bed? Not helping.

But when my ex steps in with his own agenda he ruins everything.

So here I am— jobless, manless, and staring at two pink lines.


Please Grump Daddy is a steamy standalone romance previously published as Fake Dating My Grumpy Billionaire. This edition has been revised and updated and is presented under a new title.
