The Exception: A Marriage of Convenience Romance (Tempt Series) by Jenna Hartley

When my former boss—a man known as a cold, heartless, billionaire—proposes to me, I think he must be joking.

Except I know Graham Mackenzie well enough to know he doesn’t joke.
He’s brooding, keenly intelligent, and fifteen years older than me. And the deal he’s offering…is no laughing matter.

I need money to save a château and fulfill a promise to my great-aunt, and he needs a wife.
After two years, if we can pull this off, we’ll go our separate ways.

It’s supposed to be a business agreement—nothing more. But the longer we pretend, the more I feel like I see the real Graham. And I find myself wishing for something real.
