Fated Bride: Uncle Became the Lover

On the day of her engagement to Gavin, Anne found him with Grace. The family had picked her out as Gavin's bride when she was a child, on the strength of her birth chart, and the engagement was that arrangement coming due. She went off and drank, and spent the night with a man who gave his name as Robert. He used the night to hold over her, and she agreed to three years as his secret lover. Robert was Gavin's uncle Arman, the youngest son of the family, and he kept that from her until he stated it in public. Anne had spent years grateful to Gavin for pulling her out of danger when she was younger, and that had been Arman as well.
