My Husband Betrayed Me With My Sister

The story

Delaney has spent her life coming second to her fragile, favored sister—until she catches her husband leaving an OB-GYN clinic with Diana, who is pregnant. The old affair Austin swore was over was always with her sister. When Delaney finally walks away, he retaliates by destroying her career, injuring her, and draining her blood to save Diana. They think she has nothing left. They have no idea what she has been quietly preparing.
