A masterclass in office love ... Stella Bradberry and Bella Chambers work for Atlantic Energy, a global oil company in London. Bella is a pretty single mother who dropped out of college and is doomed to work as an invisible assistant to a series of men of half her intelligence. Stella is twenty years older, about to get a seat on the board, and is the original no-glass-ceiling, high-achieving, multi-tasking mother of two. Everyone admires her; she's so straightforward and sensible. So what possesses both women to embark on pole-axing, heart-wrenching affairs with men they wouldn't have looked twice at outside the office?
