His Secret Baby by Layla Holt

Even good girls fall in love and make mistakes. Some that lead to life altering secrets.
A year and a half ago, Leah did the most stupid thing she had ever done. She shed all the values that her parents had taught her and did the one thing she had vowed never to do.
Now two and a half years later, she has matured and can stand on her own two feet. And she has the one little man who means everything to her and she to him.
Except, she’s not enough. He needs his dad.
Adrian can’t believe that she’s back. Leah. The woman he spent a weekend with and who he fell hopelessly in love. Then she disappeared. For one and a half years.
He knew how long it had been because he counted every single day.
How dare she try to waltz back into his life after ruining all women for him?
He’s determined to keep away…until he meets a gorgeous hazel eyed little boy – his son.
