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 smarts. Stella is twenty years older and about to get a seat on the board: she's the original no-glass-ceiling, high-achieving, multitasking mother of two. Everyone admires her - she's so straightforward and sensible. So what possesses both women to embark on all-consuming, heart-wrenching affairs with men they wouldn't have looked twice at outside the office? Suddenly these two sharp, intelligent women are telling lies to friends, loved ones and workmates, and risking friendships, marriages and careers to follow their hearts.
