Lexi wakes up in a hospital bed after a car accident, thinking it's 2004 and she's a twenty-five-year-old with crooked teeth and a disastrous love life. But, to her disbelief, she learns it's actually 2007 - she's twenty-eight, her teeth are straight, she's the boss of her department - and she's married! To a good-looking millionaire! How on earth did she land the dream life?!

She can't believe her luck - especially when she sees her stunning new home. She's sure she'll have a fantastic marriage once she gets to know her husband again. He's drawn up a "marriage manual", which should help. But as she learns more about her new self, chinks start to appear in the perfect life. All her old friends hate her. A rival is after her job. Then a dishevelled, sexy guy turns up ... and lands a new bombshell.
