Liz Harper's to-do list as boss of Happy Maids:

• Drive to new client's palatial Miami beach house, armed with housekeeping kit

• Try to stay upright when discovering he is none other than Cain Nestor—reclusive millionaire and infuriatingly distant ex-husband…

• Keep tight-lipped about the secret that made you walk out on your marriage

• Let him see the new you—successful business owner. Don't let on that he's making your heart beat twice as fast as normal!

Above all, remember to be professional—you're not here for romance!
