A Hazard of Hearts by Barbara Cartland

Widowed Mrs. Mansforde and her younger daughter Philomena (or Mena for short) are pleasantly surprised when elder daughter Lais returns unannounced to the family home. They have not seen her for an age, not even at her fathers funeral. And the news she brings is not so pleasant as it seems that she too has been widowed, but already has another wealthy and prestigious husband in her sights, the highly respected Duke of Kernthorpe.The Duke, who is much older than Lais, has invited her to bring her mother to meet him, an invitation that Lais does not extend to young Mena, seeing how beautiful she has become. Mrs. Mansforde insists that Mena goes with her and then it is decided that she will pose as her mothers employed companion.Once at the Dukes Castle Mena goes for a walk in the garden and then sees a stallion and rider galloping towards her. The horse is clearly out of control and throws the rider so Mena rushes over to see if he has been hurt. He is a handsome young man and when he looks up at Mena he thinks, because she is so beautiful, that she must be a Greek Goddess. He is then most impressed when Mena calms the stallion down by talking to him in a quiet gentle voice.At the Dukes Castle love is to take each of the three women, Mena, Lais and their mother, by surprise and brings them ultimate happiness in the form of entirely unexpected suitors.And it seems that Fate has brought them together at the magnificent but mysterious Kerne Castle.
