Hiding Out — Nicole Andrews Moore

A billionaire workaholic. A personal assistant running from her past. One treacherous chance at a future.

After a bad break up, Samuel Davenport throws himself into running his family's New York based advertising agency. He has little interest in women until Haley becomes his personal assistant. Soon, he's intrigued by her mind, her natural abilities for the business, and why she works so hard to hide her beauty.

Haley moved to the city New Year's Day to hide, recover, and build a new life far from her past. She alters her appearance, ignores her ambitions, and focuses on surviving one day at a time. This worked well, until Sam tries to uncover all of Haley's mysteries. 

Sometimes playing hard to get is a defense mechanism. Sometimes getting too close exposes a person to danger. Sometimes the past should be left alone.
