Who Is Sunny Caldwell? And Why Did She Fire the Nanny? Sunny Caldwell is a determined-to-succeed woman who owns a grocery-shopping service. She has two rules: Business first. Personal life second. Never get involved with a client. She followed those rules right up until the day she fired the pinch-faced nanny Chase Monroe-her newest client-had hired sight unseen. That meant she had to help Chase take care of his orphaned nephew and niece. Of course, she reasoned, then Chase could introduce her to all the right people. The only problem was that Chase and his ready-made family made her forget all about her rules .
