Dog walking was supposed to be Katie’s easy third job. When she answered the ad, she had no idea she’d be working for Clay “The Grinch†Colson—recently retired baseball superstar. He’s every bit as intimidating as the scowl he’s famous for, and Katie believes the rumors she’s heard about how mean he is are true—until she sees him with his overgrown, crazy Boxer, Dixie. Lucky Katie gets completely unexpected, front-row seats to a side of Clay the tabloids never captured. Every. Single. Morning. And the more she’s exposed to his gruff affection, the more she can’t help thinking there’s so much hiding behind that scowl… The more she wonders what she’d have to do to have him call her his good girl. Every morning, the sexiest woman he’s ever seen comes to his house and calls him Daddy. Sure, she’s his dog walker, but that doesn’t mean she has the right to sashay into his world every morning, plant that saucy little gaze on him, and say, “Good morning, Daddy.†Now that’s all he can think about—being her very dirty daddy.
