Tragedy had struck Flynn O'Roake twice recently. He'd been widowed, and his eldest daughter and her husband had been killed, leaving Flynn to raise their orphaned son. Flynn was too emotionally raw to feel like the world's greatest anything- and at forty five, he sure didn't feel old enough to be the world's greatest granddad! Single mom Susanna Troy thought Flynn was the best looking grandfather she'd ever seen, and she wasn't about to be put off by his aloof attitude. She sensed that his gruff demeanor masked a deeper hurt, a grief she knew too well. Flynn needed her help to let go of the past and to realize that what they had together was the world's greatest love. . .
