Nocturna. City Of Night

When Hope's younger sister Jenna stops sending their daily I'm alive, love you message, Hope knows something is terribly wrong. Refusing to accept the police's indifference, she follows Jenna's last known location to a foreign city-only to uncover a nightmare far darker than she ever imagined.

Her search leads her into the shadows of Nocturna, a hidden vampire kingdom known as the City of Night, where humans are not citizens but commodities. Jenna was taken there to serve a sinister purpose, prized for her rare blood and kept as property within a cruel and seductive court. Hope's desperate attempt to save her only ensnares her in the same deadly world.

Dragged before the ruthless Vampire King and his dangerously alluring brother, Lucas, Hope discovers that Nocturna is a realm ruled by ancient laws, brutal power, and twisted desire. As court politics sharpen and obsession takes hold, Hope learns that Jenna was never meant to leave-and neither was she. When the king offers a merciless bargain-Jenna's freedom in exchange for Hope's life and obedience-Hope is forced to sacrifice everything.

But the arrangement is far from simple. Lucas, furious at losing the human he already considers his, makes his claim known, and Hope soon realizes she is no longer just a prisoner in Nocturna-she is the centre of a growing struggle between two powerful monsters. In a city built on blood, hierarchy, and ownership, Hope must navigate cruelty, seduction, and survival while holding onto the one thing they cannot easily take from her: her will.
