Seventeen year old Katie is about to discover a devastating family secret ... Katie is the apple of her mother's eye, and as she is being groomed to take over the Arcadia Hotel - the family business - she has every reason to feel happy with her life. So the news that Kitty, the woman she has always called Mum, is not her real mother comes as an earth-shattering blow. And when Celia, her natural mother, re-enters Katie's life her world is turned completely upside down. She feels she must leave the Arcadia - to which she now has no right - and move in with Celia. With her fondness for ballroom dancing and a flutter on the horses, this new Mum could not be a greater contrast to the old. Katie is tormented by her divided loyalties and a question Celia will not answer - who is her real father? (Note: Originally published as Somebody Else's Girl).
