The Undomestic Goddess by Sophie Kinsella (2006, Paperback, Reprint)

Samantha Sweeting is a 20 something workaholic attorney who has just made one of the biggest mistakes of her life and wrecked any chance of a partnership with her company (you'll have to read about that boo boo)! Well, Sam is going into meltdown so she leaves her London office and walks like a zombie to the nearest train and gets aboard, not knowing where she is going, and she couldn't care less. She finds herself in front of a beautiful house and rings the door for directions, but is mistakenly taken for the new housekeeper. This book just gets funnier! Anyway, her employers have no idea that she is a lawyer and not the housekeeper they were expecting and on top of that Samantha decides to fake her way through the job, even though she doesn't even know how to turn an oven on, much less cook. She also can't sew or iron. Taking a deep breath she learns to cope with some unexpected help and puts her life back into perspective along the way.
Ms. Kinsella wrote all the "Shopaholic" books in case the name sounds familiar. This book is hilarious and I breezed through it, very sorry it ended! Loads of great fun!
