My Husband is the Darknight Warlord

Lira Greythorn is the last survivor of her noble line, and the only one who still carries an ancient codex capable of reshaping the entire vampire order. That power makes her a target among the Valen clan, whose rulers would prefer the book never resurface. Her hidden identity and the book's unmatched power pull her into a dangerous contest for control of the vampire world. Every step forward exposes her to a rival faction eager to claim what she guards.
