Pining For My Ex’s Dad by Daniella Cole

Riley is twenty-one and still terribly inexperienced. She also has a tendency to grow bored with things quickly, picking up hobbies and interests and then forgetting them soon after. She can’t sit still. She loves moving and being in the thick of things. Her one and only boyfriend was the exact same way, but this meant he never stayed faithful.
But he’s old news.

One thing she hasn’t forgotten, though?
His dad.

Mark is handsome, powerful, kind, and alone. He’s sick of hangers-on, women wanting him for his money, and all of the trappings of his high-class lifestyle. He’s also Riley’s ex’s dad, which means he has a unique view of this intriguing younger woman.
Riley has an idea. Home from college for the summer, she decides she needs to make Mark hers. She trusts him, she knows he’s a good man, and she wants her first time to be special — even if she can only have him for one night.
She has no idea that Mark has other plans for her.
