This billionaire is completely unprepared to learn he has a son in this secret baby romance by USA TODAY bestselling author Heidi Rice.

The secret is out:
He's a father!

Crashing his half sister's wedding, Ross De Courtney is in for a shock. His gaze is quickly drawn to unforgettable Carmel O'Riordan-and to the child who looks undeniably like him! Then Carmel drops an ultimatum: be a father to their son or disappear.

Forever changed by the loss of his mother, lone-wolf Ross has made sure that children will  never be in his future. He's always believed he isn't capable of the love Carmel and their child deserve. Even their extraordinary connection isn't enough to change that. Is it?
