Caroline Walker has it all. At 42, her immaculately groomed looks and toned body belie her age. She's wife to City trading sensation Les Walker, mother to their teenage daughter, Zoe, and a successful international entrepreneur with a string of luxury accessory boutiques. But when Caroline learns that Les has been having an affair, her perfect world falls apart.

Now divorced, Caroline is unexpectedly single - something she hasn't been in a very long time. With the help of Maryanne, her outgoing and ex-Hollywood starlet friend, she is introduced to a hectic social life and Caroline discovers her missing twenties . . . and the young men she should have been dating then, too - including the beautiful, sensitive male model, Adam, who is almost the same age as her daughter.

But when she finds herself in a situation she thought she'd never have to worry about, Caroline has to answer some big questions about her life - again.
