And I'm his ex who can't say no to him.

Ten years ago Carson Knight was my one great love, but he abandoned me without a trace.

Now he's a billionaire single-dad in need of a temporary wife.

And he's at my house on one knee with a proposal ...

Marry him, so he's more likely to win full custody of his daughter, keeping her safe from her unstable mother. In return, he'll take care of the medical expenses for a surgery my father needs to survive.

Reluctantly, I agree to tie the knot, on one condition. Once those custody papers are signed, we go our separate ways. Because he's even more gorgeous, charming, and sweeter than he was back then, and I don't trust myself not to fall for my fake husband.

Especially when I hear him say "my wife."

Or feel his hands on my skin. Taste his kiss or see the way he looks at me with those blue eyes and know that our carefully crafted rules will shatter.

Right alongside my heart.
