Sasha Henshaw can't believe her luck when she lands a job at Montgomery's, one of London's most prestigious companies. Working for 24-year-old Alastair Montgomery isn't easy, though, especially when he acts more like a friend than a boss. 

Assuming the role of his right-hand woman, Sasha finds herself deeply involved in Alastair's life, witnessing everything from his struggle to make his father proud, to his heartbreak over a relationship that ended three years ago.
 
But when the company is thrown into the spotlight, the lines between professional and personal relationships become blurred, and Sasha realises she's close to being wrapped up in an office affair that doesn't stop when the clock strikes five.
