Widowed firefighter Danny Santori needs a miracle. Or at least a full-time babysitter who can handle his four lively kids. With a son and daughter to raise, busy landscape designer Tessa Doherty could also use some divine domestic intervention. All they have to do is take turns watching each other's children. What could be simpler? Doing double duty as a stand-in nanny is wreaking havoc with Tessa's life. And her irresistible attraction to the roguishly charming single dad is a complication the fiercely independent career woman doesn't want or need. Danny isn't trying to stand in the way of Tessa's dreams and goals. But he's hoping she'll see that five plus three equals...one family!
