Marry Me, Kate

Description for MARRY ME, KATE by Judy Christenberry:

Kate O'Connor is desperately trying to revive her late father's luck at The Lucky Charm diner by converting it into a catering business. Only one problem stands in the way of her dreams: money. Desperate, she appeals to wealthy socialite businessman Will Hardison for assistance in the form of a business grant. But Wil has a better idea. All Kate has to do is marry him, in name only, for one year, and he will make sure her business is a success. Sounds like a great deal on paper. But what happens if one of them should happen to fall in love?
