The Regrettable Mistake is book 2 in the Cheating Hearts Series, but all books in this series are complete stand alone stories.

Ollie
I let nostalgia rule as I made the biggest mistake of my life!
Not knowing how to fix the initial problem led to more problems before it was all over. I was smarter than this.
Now, I had to find a way to silence my ex and convince my wife that my feelings, while faked in the beginning, were more than real.
I never realized that one mistake could careen into something that would change all of our lives forever, but that is exactly what happened.
It was the worst mistake of my life.
My wife was both the problem and solution, if only my ex wasn't standing in the way.

Steph
My twin warned me that Ollie didn't love me.
I should have listened.
My husband only wanted a convenient, live-in nanny/new mommy for his son who his ex-girlfriend abandoned with him when she went to go live her dreams of being a big-time actress.
As I stared at the evidence of my secret while waiting on my husband to come back home again, I knew everything my twin told me was true. I was a convenient wife and nothing more. I had to decide if it was time for me to be selfish or to continue to live the lie for more than one child.

*If you do not like to read stories where a main character cheats on their significant other, then this is not the book for you!
