Lucy is married, she has children, but she is haunted by the feeling that somewhere along the line her life's gone wrong. One cross, hectic day, she has a car crash, and when she wakes, she is eighteen again and lying beside the man she's always loved - the one she never kissed. She wants to do it now. She thinks she's in control.

But she's not, and she has far more to lose than she realised.
