Double-marked: Luna's Revenge

Luna Talia sacrificed her blood to sustain their decade-long marriage, only to catch her husband marking his lover. Publicly humiliated and trapped in a sack, she endured torment while he watched coldly with his lover by his side. She left a moonstone necklace holding the truth and divorce papers. When he saw the papers, he broke down and rushed to her chamber — only the necklace remained; she was gone forever.
