Kate Forrest is invisible. Ned, the husband she adores, doesn't seem to know she's alive, and her two charming children have grown into stroppy adolescents. Her boss is suddenly shunting her towards career Siberia, and her demanding mother is never off the phone. With her fortieth birthday fast approaching, all Kate wants to do is run away from the lot of them. And so she does. On impulse, Kate walks out of her job, her family and her life, and gets on a plane to Italy. With no ties and no responsibilities, she soon finds herself deliriously caught up in La Dolce Vita and the arms of a man barely half her age. But when the unthinkable threatens her family, Kate is brutally forced to choose between her past and the future.
