Only One Mistake (Only One Series Book 6) by Natasha Madison

A one-night stand gone wrong?

Michael
Being traded after fighting with your coach on air isn’t exactly a good look.
With one mistake under my belt, I knew I needed to focus on the game and nothing else.
But everything changed when I went to pick up my niece and came face-to-face with my very pregnant one-night stand from six months ago.

Two pink lines changed all my plans.
So did the guy I had a one-night stand with, a man who made me laugh and smile, a guy who I called to share my unexpected news with, only to find out his number was no longer in service.
Once more letdown by the opposite sex, I figured I was doing this on my own.
Then one day, I was staring into the eyes of the man I hated, the father of my baby.

All it took was only one mistake to change everything.
