What do you when, three weeks from your wedding, a blackmailing aunt leaves you holding the baby?

Faith Bridges should be wedding dress shopping with her bridesmaids, finalising the menu for the reception, house hunting. Instead she's up close and personal with Harry March - the last man on earth she’d trust with her heart - a fractious baby and a four year old diva.She and Julian may not have had the most conventional of courtships but he’s wise, responsible and utterly dependable. The exact opposite of Harry, who thinks that all he has to do to get her to stay and take care of his sister's children is to tease her, charm her and, when that doesn’t work, make love to her.

It won't work; Faith knows that love is like meringue — all sugar and air, and about as substantial. And she has made a promise that she isn’t about to break. So why does she find it so hard to walk away?
