Challenging Jayce by Elizabella Baker

As a romance author, Kennedy knows all about happily ever afters. She just never thought they were for her. She was happier writing about her fantasies than living them out.
Until Jayce Pierce came along.
But Jayce is nothing like the book boyfriends she’s used to writing about. He’s grumpy, full of hate, and has a chip on his shoulder.
All Jayce ever wanted in life was a family he could take care of. But when his ex-wife cheated on him, he vowed to never make that mistake again.
Now fifteen years later, he was about to learn that everything he thought he knew had been a lie. He has a fifteen-year-old son named Michael who was raised by another man. And Michael’s life could now be in danger.
It will be up to Jayce to find what other secrets have been hidden from him and how he can keep his son from the consequences of his mother.
