Cassandra Woodson is lost. Cassie discovers that taking a thankless temporary job examining mail for a big fraud claim is the only way she can pay her expenses after taking an epic slide down the corporate ladder. The daily grind intensifies everything she lacks in life?love, friends, stability?leaving her with too much free time to dwell on the errors that led her to this situation. The romantic (and completely private) emails between Forest Watts, a partner at the business, and his alluring wife, Annabelle, grab her attention as she is sifting through a never-ending flood of emails. Knowing she shouldn't read them, Cassie refrains. But that was only one glance. When the door opens, she discovers that she is unable to turn away. Every day, from her drab desk 20 floors below Forest's corner office, Cassie analyses their correspondence. She can view each loving message they send to one another with just a few mouse clicks. Cassie discovers new meaning and satisfaction by peeping into their ostensibly perfect lives, savouring their love of vintage wines, morning juice presses, and extravagant dinner parties hosted in their majestic Westchester house. She doesn't have any secrets. or so she believes. Her admiration quickly escalates into all-out mimicry, because she wants this life more than anything. Maybe if she plays make-believe long enough, it will become real for her. But when Cassie orchestrates a ?chance? meeting with Forest in the real world and sees something that throws the state of his marriage into question, the fantasy she?s been carefully cultivating shatters. Suddenly, she doesn?t simply admire Annabelle?she wants to take her place. And she?s armed with the tools to make that happen.
