The story follows Nina Langford, the legitimate Langford family daughter. Abandoned in a blizzard by her father at six for her so-called inferior bloodline, she was adopted by Vincent, leader of the Iron-Tooth werewolf clan. After sixteen years, she was recalled to the Langford family by her grandfather.
Nina turns out to be a rare vampire-werewolf-witch triple hybrid with formidable powers. Secretly known as “Jade”, she amassed immense wealth and influence, owning a biotechnology firm that controls US vampire blood supplies and a prestigious auction house. Her second brother Marcus, a core member of the sinister Chimera organization, harbors malice against the Langfords. Manipulating his adopted daughter Rachel’s jealousy, he stirs up chaos, colludes with dark wizards, and attempts to trigger a vampire-werewolf war to destroy the family. With the help of her lover Sebastian, friend Yolanda and adoptive father Vincent, Nina defeats Marcus and unveils his conspiracy during the Blood Moon blessing. She finally yields the blessing to her brother Evan, wins wide recognition, and establishes her status as the legitimate Langford heir and a powerful figure in East Coast vampire society.
