Lizzie Buckley has a life many women dream of - a gorgeous husband, wonderful home and beautiful (when they're not fighting) three year old twins.
But there's a snag. It's not that Lizzie has gone off marriage, as such. Well, not exactly. She's just gone off the skin-to-skin, body-fluid-exchange aspects of marriage. Ever since the birth of the twins, she's had a fantasy about locking herself in her bedroom for 24 hours alone with a good book and a box of chocolates. Unfortunately, her husband James doesn't understand her feelings.
And when Lizzie hits 'send' on the wrong email, suddenly everything starts to unravel. With the word 'divorce' ringing in her ears, Lizzie finds herself moving out and embarking on a totally different life - new house; new neighbours; no husband.
But despite transforming her body, her neglected career and her libido (courtesy of the local landscape gardener), Lizzie can't get over her soon-to-be ex. Still mulling over her failed marriage, Lizzie can't help wondering whether she was ever good enough for gorgeous James.
Or, as her mother-in-law suggests, was she just the wrong sort of wife?
