The Undomestic Goddess by Sophie Kinsella (2005)

Having left the book I was reading at home, I picked this up at the airport and have finished it in the long waits and on the plane. I was looking for something light, after all the evil in my recent books. I kept looking at Kinsella's books, but was not that interested in reading about a shopaholic. This was perfect. Samantha is a brilliant young lawyer in one of the top law firms in London, poised to become the youngest partner, when she makes a huge and unforgivable mistake. Shell shocked she wanders out of the office, through the streets, ends up at a train station, gets on the next train and doesn't even know where she is when she gets off. She knocks on a door to get a drink of water and gets hired as their housekeeper - not knowing anything about cooking, cleaning or laundry. But she learns - in a delightfully funny way and finds that there is more to life than an intense career that doesn't give you any time away from your phone, no free evenings or weekends. And of course there is a love interest - the gardener Nathaniel.
