Book ~ "Undomesticated Goddess" (2005) Sophie Kinsella

From Amazon.com ~ Samantha Sweeting is on the verge of partnership at the prestigious London law firm Carter Spink, the Holy Grail of her entire workaholic life. But when she finds she has made a terrible costly mistake just before the partnership decision, she's terrified of being fired. In a fog, she stumbles out of the building and onto the nearest train, which drops her in the countryside, where she wanders to a stately home. The nouveau riche lady of the house mistakes her for the new housekeeper and Samantha is too astonished to correct her. Numb and unable to face returning to London, Samantha tries to master the finer points of laundry, cooking and cleaning. She discovers that the slow life, her pompous but good-hearted employers and the attentions of the handsome gardener, Nathaniel, suit her just fine. But her past is hard to escape, and when she discovers a terrible secret about her firm, and when the media learns that the former legal star is scrubbing toilets for a living, her life becomes more complicated than ever.

A fun read! It's the latest by the author of the Shopoholic series (which I find very funny).
