Book 2 - Echo in the Dark He reads the minds of killers. She hunts their truths. Together, they might destroy each other-or save what's left. Zhou Anxin has spent his life studying monsters. A forensic psychologist known for his cold precision, he dissects motives and minds with surgical detachment. Every case leaves him a little emptier, a little quieter-and he prefers it that way. Min Yooin doesn't do quiet. An investigative journalist driven by instinct and moral fire, she's chasing a serial case that the police have buried under bureaucracy. Her only lead? The reclusive profiler who wants nothing to do with her. When their paths collide, so do their beliefs. He trusts data. She trusts her gut. He sees people as patterns. She forces him to see humanity again. But as the murders draw closer, lines blur. The hunter and the hunted begin to look the same-and the darkness Anxin has always kept at arm's length starts whispering back. Because some cases don't just change you. They consume you. And Min Yooin might be the only thing standing between Zhou Anxin and the abyss he's sworn to understand.
