Wife in Name Only

Innocent and pleasant story. A woman attempts revenge, setting a man up to marry a woman who he thinks is his ideal but who has an unknown stain in her lineage. He is proud and believes he must sacrifice his bride and his heart to uphold the purity of his own race...is there any hope for them? Perhaps they will both die of disappointment...unless the woman who deceived them with the false grounds for their union in the first place might have been mistaken in the past of the young wife...will justice be done?
About a 3.75 for me. The ending is really sweet, though!
