Y/N’s ordinary life shatters when she witnesses a calculated act of violence by Silas Noctryn, a lethal man from a hidden world where witnesses are erased. Instead of killing her, Silas hesitates, drawn to her defiance and composure, and kidnaps her to keep her silent. As he hides and protects her, he breaks every rule he’s ever lived by, placing both of them in danger. Trapped between fear and obsession, Y/N becomes the one thing Silas can’t eliminate—and the one thing he’s willing to protect.
