In the land of Nyxhaven, where the sun has long been darkened by dark magic, the moon rules supreme and night is eternal. Amidst this perpetual twilight, Gloria hides a deadly secret. As a vampire within the Beltraine Sisterhood, she must conceal her true nature or face a gruesome death. Furthermore, Gloria is the only Channeler among the witches of Beltraine, her unique energy essential for the powerful ritual known as the "Chain of Glory," which fuels the magic used to kill her kind. Forced to feed nightly on her best friend, Faelina — the only person aware of her terrible secret — Gloria struggles to curb not only her bloodlust, but her ever-blossoming fondness toward the fragile girl. As the tension heightens at Beltraine, four royal vampire families fight for the throne. The current Vampire King, Draven Blackcross, tightens his grip through schemes and cruelty. Unbeknownst to him, his daughter, Tamsyn harbors a dangerous secret of her own—she is a witch. Should Tamsyn's true nature be discovered, it would spell disaster not only for her but also for her father’s reign. Amidst the brewing chaos, the vampires plot a deadly assault on Beltraine. Draven, ever the strategist, decides to send Kain, Tamsyn's beloved boyfriend, on this perilous mission. However, Tamsyn learns through a clairvoyant vampire that Kain is doomed to die on the mission. Desperate to save him, and to protect her secret, she must navigate a web of deceit, danger, and her own burgeoning powers.
