Detective Jameson, once a timid and kind man, transforms into the ruthless "Darkest Officer" after drinking water given by a mysterious woman. He becomes a vampire who feeds on human blood and anxiety, and marries Emilia, a woman auctioned off to him. Despite treating her poorly, Emilia discovers his secret and begins to fall in love with him. Jameson, however, doesn't reciprocate her feelings, instead demanding she sleep with his friend's stepdad to prove her love. As Jameson's powers grow, Emilia becomes his anchor, calming his ruthlessness, but he struggles to acknowledge his feelings for her. Will Jameson fight his hunger or will he succumb to it?

When seven coworkers vanish during her first night shift, Lyra Duvell discovers Halcyon Gate isn’t just a research facility — it’s a t between two mirrored timelines. And she’s the impossible glitch holding them together. Hunted by soldiers, haunted by a stranger who fades like static, and betrayed by the scientist who created the Gate, Lyra learns the truth: her alternate-self died ten years ago… yet she somehow survived. With her best friend Rae — a girl who has no alternate version at all — Lyra falls into collapsing worlds, ancient prophecies, and a war between timelines. And when Rae’s existence threatens to destroy reality, Lyra must choose between saving her or saving the world. But some bonds go deeper than destiny. And some echoes refuse to fade.
