When Emerie finds an intruder in her new Park Avenue office, she calls 911. Turns out, Drew is the rightful occupant-- a divorce lawyer who was on vacation while the space was being renovated, and a scammer swindled Emerie out of ten grand. Drew offers her a job answering his phones while his secretary was out. When she overhears the advice he gives his clients she gives him a piece of her mind. She never expected her body to react every time they argued. The only thing the two had in common was the space they were sharing... and an attraction that was getting harder to deny by the day.
