Cassie Lucas, a red-headed imp, loves dogs so much she sleeps in flannel puppy covered pajamas. A secret study for her psychology doctorate makes her job of dog-walking more than just a way to make money. Her brood consists of six interesting animals and their owners, all residents of her posh condo building on Lake Shore Drive in Chicago. But none of them is as interesting as the cool, distant, Ryan Winston, a multi-millionaire who occupies the penthouse. Ryan Winston's two goals in life are to accumulate wealth and to avoid the debutantes who think he's perfect husband material. When he meets Cassie, he has a devil of a time remembering his goals. He has no idea she's actually Cassandra Lucas Sykes of Sykes Steel Mills, until she unknowingly bests him in a real estate deal. Then the fun begins!
