The Undomestic Goddess by Sophie Kinsella
Samantha Sweeting is always at work… Well, at least it feels that way. Working at one of the highest-considered firms in London, Samantha is on her game. Yes, her desk is a mess, but she is 100% on her game. However, when she starts cleaning off her desk, she notices a memo on her desk that could completely derail her career. Without realizing it, she shuts down and gets on the train–finding herself in the middle of nowhere.
