Auditing the Grumpy CEO: An Off Limits, Single Dad Romance

by Isla Wren

I fell in love with a man I was hired to ruin.He’s not just my new client—he’s the single dad who looked at me like I could save him. And the off-limits, grumpy CEO who thinks I’m a sunshine-y threat. I didn’t think anything could be more complicated than being hired to find cause to fire him.

Then a storm trapped us together, and one reckless kiss broke all my rules. I started seeing the man behind the stone walls and the desperate love he has for his little girl. The more I learn, the more I’m sure Beckett isn’t the villain. The more I fall for him.

And that’s when my world implodes.

His brother just leaked footage of us together to ruin his brother’s reputation—and his chances of keeping his daughter. To save him, I have to risk my entire career. But what do you do when your lover’s family is the real enemy? And what do you do when they're willing to do anything to get what they want—even if it means tearing your world apart?

Auditing the Grumpy CEO by Isla Wren

I enjoyed reading Sienna and Beckett's story. I enjoyed the storyline and thought that it was well written. It is a slow burn single dad story that pulled me in from the first chapter.

Out of all of the books I have read by Isla I think that Sienna and the grumpy single dad billionaire Beckett might be my favorite so far. The storyline and romance kept me enticed on what was going to happen next. This is a must-read book.
