All In With Me by Mary A. Wasowski

After eighteen years playing in the NFL and with his fortieth birthday fast approaching, pro running back star Patton James is on his way to his second career Super Bowl championship. However, all that everyone is talking about and wants to know is if this will be the year he retires and says goodbye to the game he loves.
But as he contemplates his future, he’s dealt with another upset involving his longtime on-again, off-again girlfriend who will no longer compete with football. When he receives a letter alerting him of her imminent departure, he is forced to reexamine his life and the choices he has made.
He’s about to play in the biggest and possibly last game of his life, but first, he has two weeks to try and stop his one true love from leaving him forever and prove to her that she is the one that has his true heart.
