A group of nineteen tourists, while traveling in Thailand, accidentally strays into a city nestled deep within a ring of mountains. All signs suggest it’s a Chinese enclave—complete with a bank, post office, shops, a police station, and a hospital. Everything a functioning city should have. Except… there's not a single soul in sight. Why is the city completely deserted? What fate awaits the protagonist? How did the tour group end up so far off course? What will they discover—and what horrors will they face? Who will be the next to fall? Layer upon layer of chilling mysteries intertwine, each more disturbing than the last— and none will be unraveled until the very end.

My sister and I are twins— the kind of twins legends whisper about: the yin and the yang. The uglier I become, the more beautiful she grows. The worse my grades are, the higher hers soar. The weaker my body gets, the stronger hers becomes. One declines, the other rises. We are like two sides of a scale, destined never to be balanced. So our parents made a choice— to sacrifice me, in order to raise a single, dazzling daughter, their pride, their shining star.
